However, developing aptamers is both experimentally demanding and time-consuming. A team of scientists from IOCB Prague, led by Dr. Marek Ondruš and <a target="_blank" rel="noopener noreferrer" href="https://hocek.group.uochb.cz/en">Prof. Michal Hocek</a>, has now developed a technology that significantly shortens the development process.“Developing an aptamer is often like looking for a needle in a haystack. Among trillions of different DNA sequences, we search for the one that binds strongly and specifically to a target molecule. Our new approach first screen for ‘aptamer families’ – hundreds of related sequences – and then identify the best-performing member of the family. This approach can reduce development time from several months to only a few days,” says Marek Ondruš.<blockquote>Video:<a target="_blank" rel="noopener noreferrer" href="https://www.youtube.com/watch?v=_3zXUeVMugU"> New technology streamlines the development of aptamers, synthetic alternatives to antibodies&nbsp;</a></blockquote>The team has also expanded the potential applications of aptamers by chemically modifying their building blocks. For example, introducing functional groups similar to those found naturally in amino acids allows the resulting molecules to combine the advantages of both DNA and antibodies: Their sequence is encoded by the order of nucleotides in DNA, while the attached chemical modifications greatly expand their ability to recognize biologically relevant targets and mimic interactions between proteins that are underlying many biological processes.The researchers demonstrated the potential of this new method using the human insulin receptor, a key protein that regulates blood sugar levels. They developed an aptamer that specifically binds to the receptor and elucidated the molecular basis of this interaction using cryo-electron microscopy. “We have shown that chemically introduced functional groups play a crucial role not only in target recognition and formation of the aptamer–protein complex, but also in stabilizing the DNA aptamer’s structure. Our findings provide new insights into how chemically modified nucleic acids can mimic key properties of proteins,” says Marek Ondruš.In the future, the technology could complement – or, in some applications, even replace – antibody-based diagnostic tools.

Here, we present a single-round selection strategy for rapid screening of multiple over-represented nucleobase-modified DNA libraries and various selection conditions, capable of identifying high-affinity modified aptamers. Double partition followed by amplification of eluted sequences, NGS analysis and clustering provides fast identification of aptamer candidates. Screening of modified DNA libraries containing modified adenine and uracil nucleotides bearing hydrophobic aromatic phenyl and indole moieties results in development of an aptamer binding human insulin receptor with sub-nanomolar affinity and exquisite specificity. Cryo-EM structure reveals the importance of each aromatic modification, either in stabilizing the secondary structure or facilitating interactions with the protein surface. This approach addresses the main drawbacks of aptamer selection and has potential for high-throughput screening and accelerating the development of next-generation aptamers for diagnostics or therapeutics.</div>

🎤Dr. Leigh Terry (University of Alabama)In this episode of Concentrating on Chromatography, we sit down with Dr. Leigh Terry from the University of Alabama to explore one of the biggest challenges in environmental analysis today: understanding—and accurately measuring—PFAS in water systems.While most regulatory methods focus on a small number of compounds like PFOA and PFOS, there may be thousands of PFAS compounds in the environment—and much of that burden goes undetected.<h4>In this episode, we cover:</h4><ul><li>Why PFAS are called “forever chemicals” (and why that label is evolving)</li><li>The limitations of targeted LC-MS/MS methods</li><li>What the fluorine mass balance problem reveals about PFAS destruction</li><li>How combustion ion chromatography (CIC) helps measure total organofluorine</li><li>Why “99.99% removal” doesn’t always mean what you think</li><li>Where PFAS actually end up in wastewater treatment systems</li><li>The most effective technologies for PFAS removal today</li><li>Why drinking water may only account for ~20% of total PFAS exposure</li></ul><h4>Key Insight:</h4>Even when analyzing dozens of PFAS compounds, researchers may only be capturing a small fraction of total organic fluorine—raising major questions about how we monitor and regulate these contaminants.<h3>Video Transcription</h3>In this episode of Concentrating on Chromatography, Dr. Leigh Terry discusses PFAS contamination in drinking water, the analytical challenges associated with measuring these compounds, current treatment technologies, and future directions for monitoring and regulation. The conversation highlights how analytical chemistry, environmental engineering, and public health intersect in addressing one of today's most discussed classes of emerging contaminants.<h4>Understanding PFAS and Their Significance</h4><h5>The University of Alabama Water Quality Research Center</h5>Dr. Leigh Terry is part of the University of Alabama's Center for Water Quality Research. The center operates an analytical laboratory focused on drinking water quality and the detection of contaminants at extremely low concentrations.The laboratory specializes in:<ul><li>Drinking water analysis</li><li>Organic contaminants</li><li>Emerging contaminants</li><li>PFAS monitoring</li><li>Water quality research</li></ul>Their work supports both research initiatives and practical solutions for water utilities and environmental agencies.<h4>Why Focus on PFAS?</h4>Although PFAS compounds have existed since the 1940s, public awareness has increased dramatically only in recent years.According to Dr. Terry, several factors contributed to the rapid growth of PFAS research:<ul><li>Increased media attention</li><li>New regulatory initiatives</li><li>Growing evidence of human exposure</li><li>Expanding research opportunities</li><li>Greater understanding of potential health risks</li></ul>PFAS are not new contaminants. Rather, society is only beginning to understand their prevalence in the environment and their potential impacts on human health.<h4>The Development of Standardized PFAS Methods</h4>One major advancement in PFAS analysis has been the development of standardized EPA methods.These methods allow:<ul><li>Consistent testing procedures</li><li>Comparable results between laboratories</li><li>Regulatory monitoring</li><li>Reliable data interpretation</li></ul>Dr. Terry notes that many of these standardized approaches began appearing around 2018–2019, providing a common framework for analytical laboratories and researchers.<h4>How Large Is the PFAS Universe?</h4>Many people are familiar with PFOA and PFOS, two of the most heavily studied PFAS compounds. However, these represent only a small fraction of the broader PFAS family.PFOA and PFOS are often referred to as:<ul><li>Legacy PFAS compounds</li><li>Original PFAS contaminants</li><li>Early commercial PFAS chemicals</li></ul>The challenge is that even minor modifications to molecular structure create entirely new PFAS compounds.Researchers estimate:<ul><li>Thousands of PFAS compounds exist</li><li>Some estimates exceed 10,000 compounds</li><li>Exact numbers depend on how PFAS are defined</li></ul>Scientific debate continues regarding classification and definition, making precise counting difficult.<h4>Why PFAS Are Called "Forever Chemicals"</h4>Dr. Terry notes that the phrase "forever chemicals" has become widely used, although she suggests the terminology could benefit from rebranding.PFAS persistence results from two key chemical properties.<h5>1. Amphiphilic Structure</h5>PFAS molecules contain:<ul><li>A water-loving (hydrophilic) head group</li><li>A water-repelling (hydrophobic) fluorinated tail</li></ul>This unusual combination allows PFAS to partition between:<ul><li>Water</li><li>Solids</li><li>Air-water interfaces</li><li>Foam</li></ul>Unlike many organic compounds, PFAS can interact effectively with multiple environmental phases.<h5>2. Extremely Strong Carbon–Fluorine Bonds</h5>The carbon–fluorine bond is among the strongest bonds in organic chemistry.As Dr. Terry explains:<ul><li>Large amounts of energy are required to break these bonds</li><li>Natural degradation processes are often ineffective</li><li>Destruction can require highly aggressive treatment conditions</li></ul>These properties make PFAS extremely persistent in both environmental systems and biological organisms.<h4>Toxicity, Regulations, and Environmental Behavior</h4><h5>Understanding PFAS Toxicity</h5>One of the biggest challenges in PFAS regulation is the incomplete understanding of toxicity.Dr. Terry explains that EPA regulations generally consider three factors:<ul><li>Presence in drinking water sources</li><li>Toxicity to humans</li><li>Availability of practical treatment options</li></ul>While some PFAS compounds are known to be harmful, many others remain insufficiently studied. Furthermore, PFAS often occur as mixtures rather than individual compounds.This creates important scientific questions:<ul><li>What is the toxicity of individual PFAS?</li><li>What is the toxicity of PFAS mixtures?</li><li>How should cumulative exposure be evaluated?</li></ul>These uncertainties continue to drive active research.<h4>What Happens to PFAS in Wastewater Treatment Plants?</h4>PFAS do not behave like many conventional contaminants.Rather than remaining fully dissolved in water, they often accumulate at interfaces such as:<ul><li>Water-solid interfaces</li><li>Water-air interfaces</li><li>Foam layers</li><li>Biological solids</li></ul>As a result:<ul><li>Some PFAS accumulate in biosolids</li><li>Some partition into foam</li><li>Some remain in treated effluent</li></ul>Their distribution depends on wastewater composition and treatment processes.<h4>Regulatory Monitoring and Targeted LC-MS Analysis</h4>Current EPA regulations focus on targeted analysis of specific PFAS compounds.Examples include:<ul><li>PFOA</li><li>PFOS</li></ul>Drinking water regulations currently establish maximum contaminant levels (MCLs) for these compounds at extremely low concentrations.Advantages of targeted LC-MS analysis include:<ul><li>Clearly defined analytes</li><li>Established regulatory limits</li><li>High analytical sensitivity</li><li>Reliable quantitation</li></ul>However, limitations remain:<ul><li>Only a small subset of PFAS is measured</li><li>Many PFAS compounds remain undetected</li><li>Total PFAS burden may be underestimated</li></ul>As Dr. Terry notes, targeted analysis provides only part of the overall picture.<h4>The Fluorine Mass Balance Problem</h4>One of the most important concepts discussed in the interview is fluorine mass balance.When PFAS degrade, fluorinated fragments may remain in the environment.This creates a critical question:Are treatment technologies truly destroying PFAS, or merely transforming them into shorter-chain PFAS compounds?To answer this, researchers perform fluorine mass balance calculations using:<ul><li>Targeted PFAS analysis</li><li>Fluoride measurements</li><li>Total organic fluorine measurements</li></ul>A successful destruction process should ultimately convert PFAS into fluoride ions rather than simply producing smaller PFAS molecules.<h4>Advanced Analysis, Treatment Technologies, and Future Directions</h4><h5>Combining Targeted and Bulk Fluorine Measurements</h5>Dr. Terry's group complements targeted LC-MS analysis with measurements of total organic fluorine.Approaches include:<ul><li>Absorbable Organic Fluorine (AOF)</li><li>Extractable Organic Fluorine (EOF)</li><li>Combustion Ion Chromatography (CIC)</li></ul>In these methods:<ul><li>Organic fluorine is captured</li><li>Samples are combusted</li><li>Released fluoride is quantified</li></ul>This provides insight into total fluorinated content, although contributions may originate from sources beyond PFAS, including pharmaceuticals and consumer products.<h4>Surprising Findings from Combined Analysis</h4>One important finding from wastewater studies was that targeted PFAS measurements accounted for only a small fraction of total organic fluorine.Dr. Terry reports that:<ul><li>Approximately 4% of measured AOF could be explained by targeted PFAS compounds</li><li>The majority of organic fluorine remained unidentified</li></ul>This suggests that environmental fluorine chemistry is considerably more complex than currently represented by routine monitoring programs.<h4>Preventing PFAS Contamination in the Laboratory</h4>PFAS analysis requires exceptionally strict quality control.Dr. Terry's laboratory routinely:<ul><li>Tests every new batch of SPE cartridges</li><li>Tests carbon tubes before use</li><li>Uses DI water blanks</li><li>Verifies consumables labeled as PFAS-free</li><li>Collects field blanks</li><li>Monitors analytical blanks throughout workflows</li></ul>These practices help prevent contamination from laboratory materials and consumables, a common challenge in ultra-trace PFAS analysis.<h4>Current PFAS Treatment Technologies</h4>Three technologies currently dominate PFAS removal in drinking water treatment:<ul><li>Granular Activated Carbon (GAC)</li><li>Ion Exchange Resins</li><li>Reverse Osmosis (RO)</li></ul>Selection depends on:<ul><li>PFAS concentration</li><li>Water quality</li><li>Local operating conditions</li><li>Utility infrastructure</li></ul>Although many emerging technologies are being investigated, these remain the most widely implemented solutions.<h4>Membrane Filtration and Pretreatment</h4>Dr. Terry collaborates with colleagues studying membrane-based PFAS treatment.Her own work focuses on pretreatment through biological filtration.The strategy involves:<ul><li>Removing natural organic matter</li><li>Reducing membrane fouling</li><li>Improving membrane performance</li><li>Extending operational efficiency</li></ul>This integrated approach demonstrates how multiple treatment technologies can work together to improve PFAS removal.<h4>Regional Monitoring Projects</h4>The University of Alabama team participates in EPA-supported monitoring efforts along the Gulf Coast.Their observations indicate:<ul><li>PFAS rarely occur alone</li><li>Multiple PFAS compounds frequently co-occur</li><li>Contamination often originates from identifiable point sources</li></ul>Examples include:<ul><li>Industrial facilities</li><li>Manufacturing operations</li><li>Military installations</li><li>Carpet manufacturing facilities</li></ul>Source identification remains a critical component of environmental monitoring programs.<h4>Future Directions for PFAS Monitoring</h4>Looking ahead, Dr. Terry sees several opportunities for improvement.Desired advances include:<ul><li>In situ monitoring technologies</li><li>Portable detection systems</li><li>Reduced analytical complexity</li><li>Lower instrument costs</li><li>Less expensive consumables</li><li>Faster analysis workflows</li></ul>Current PFAS testing requires substantial expertise, specialized instrumentation, and rigorous quality control, making widespread implementation challenging.<h4>Dr. Terry's Perspective on Long-Term Solutions</h4>When asked what major PFAS challenge she would most like to solve, Dr. Terry offered a broader perspective.Rather than focusing solely on remediation, she emphasized prevention.Her view is that society should:<ul><li>Better evaluate chemical toxicity before commercialization</li><li>Assess risks before large-scale deployment</li><li>Reduce introduction of harmful compounds into the environment</li><li>Support utilities tasked with contaminant removal</li></ul>She notes that water utilities often bear the responsibility of removing contaminants they did not create, highlighting the need for broader societal and regulatory support.<h4>Final Thoughts</h4>Dr. Terry encourages consumers to:<ul><li>Learn where their drinking water originates</li><li>Read annual water quality reports</li><li>Stay informed about local water quality</li><li>Consider appropriate home filtration where needed</li></ul>At the same time, she emphasizes confidence in municipal water systems and the importance of continued investment in water quality research, monitoring, and treatment technologies.<h4>Conclusion</h4>PFAS remain one of the most complex challenges in environmental chemistry and water treatment. Through advanced analytical methods such as LC-MS/MS, combustion ion chromatography, fluorine mass balance approaches, and large-scale monitoring programs, researchers like Dr. Leigh Terry are helping improve our understanding of these persistent contaminants.The interview highlights that solving the PFAS challenge will require a combination of better analytical tools, improved treatment technologies, stronger regulatory frameworks, and a greater emphasis on prevention before contaminants enter the environment.<blockquote>This text has been automatically transcribed from a video presentation using AI technology.

ECOM ECP2100 Preparative Pump

 Preparative HPLC pump with a flow-rate range up to 100 ml/min. 

<div style="display:block;" aria-labelledby="tab_item-0">Innovated pumps ECP2100 work as isocratic pumps and together with a gradient box also as a gradient pump. These powerful and durable pumps are suitable for preparative applications in low- and high-pressure liquid chromatography across the chemical industry. They are designed with 2 pump heads connected in parallel with a piston diameter of 3/8”.Many improvements make these pumps more reliable, including a new learning algorithm for pulsation suppression and a leakage sensor. New material versions have been added-in, beyond to stainless steel A316L, also Hastelloy, titanium and PEEK for biocompatible applications.The pumps can operate in two modes, i.e. using constant pressure or using the newly added option of constant flow rate. The ECP2100 pump now has an innovated spring-loaded outlet check-valve.<h4>Gradient function</h4>These pumps work as isocratic pumps, and, together with ECOM gradient boxes, they also work as gradient pumps. Gradient boxes ECB2007, ECB2007PC are equipped with a four-way gradient mixing valve and must be ordered together with the pump. These sophisticated units allow for achieving a precise low-pressure gradient, i.e. gradual changes of solvent composition by mixing up to four liquids at the pump‘s entry. The gradient profile can be defined via a computer or manually using a display and a keypad. Without the use of a gradient box, the pump works as isocratic, with the option of one solvent and the composition of the mobile phase being chosen by the user.Customers can use the pistons‘ back-washing function, after working, for example, with a buffered mobile phase.<h4>Seals</h4>All pumps are delivered with GFP (PTFE) seals by default.

ECOM ION-QN and ION-QD Chiral HPLC Columns

 Weak Anion-Exchanger (WAX) stationary phases for reliable chiral separation of organic acids and amino acids. The most efficient approach to purify and resolve even the most troublesome enantiomeric mixtures.

Weak Anion-Exchanger (WAX) stationary phases for reliable chiral separation of organic acids and amino acids.&nbsp;We introduce our own generic series of weak anion-exchangers, based on tert-butyl-carbamoylated Cinchona alkaloids quinine (QN) and quinidine (QD). Our Chiral ION-QN and Chiral ION-QD columns contain a well-balanced pair of pseudoenantiomeric chiral selectors, designed to efficiently separate enantiomers of acidic compounds. These columns represent the most efficient approach to purify and resolve even the most troublesome enantiomeric mixtures.<h4>Applications</h4><ul><li>Chiral ION-QN and Chiral ION-QD are ideal for enantioseparations of chiral acidic compounds, including:</li><li>N-protected amino acids</li><li>Aminophosphonic &amp; Aminosulfonic acids</li><li>Lactic &amp; Thiolactic acids</li><li>Clenbuterol &amp; Thyroxine</li></ul><h4>Key Benefits</h4><ul><li>Provide better separation power and increased enantioselectivity (in comparison to other available alternatives)</li><li>Allow elegant switch of the elution order of enantiomers</li><li>Demonstrated high stability against all common HPLC solvents</li><li>Enable enhanced method development</li><li>Available at analytical and preparative scale</li></ul><h4>Columns</h4><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/ECOM_Chiral_HPLC_Column_ION_QN_and_ION_QD_6_085a58fc5e.jpg" alt="ECOM: Chiral HPLC Column ION-QN and ION-QD" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_ECOM_Chiral_HPLC_Column_ION_QN_and_ION_QD_6_085a58fc5e.jpg 245w," sizes="100vw" width="1059" height="531"><h4>Features&nbsp;</h4><ul><li>Max. pressure: 5800 psi (400 bar)</li><li>Particle size: 3 or 5 μm</li><li>pH range: 2 to 9</li><li>Pore size: 120 Å</li><li>Surface area: 300 m²/g</li><li>Max. temperature: 60 °C</li><li>Packing material: Spherical, Fully Porous</li><li>Carbon load: 13.0 %</li><li>End-capped: Yes</li><li>Product line: ION</li></ul>The mobile phase composition (methanol-formic acid-ammonium formate) has been optimized for preparative applications to provide high column loadability, fast analyte elution, and good peak shape. Moreover, the buffer allows for simple product harvesting by solvent evaporation and subsequent ammonium formate sublimation 50 °C / 10 torr.The anion exchangers are perfect for the purification of organic acids and their chiral separation. They are very efficient in the chiral resolution of amino acids, but also other derivatives, such as amino phosphonic acids. Aminophosphonic acids are important precursors in the synthesis of phosphopeptidomimetics, which may potentially serve as new-generation pharmaceuticals.
