Tasty beer starts with knowing what’s in your hops. Explore how online SPE makes bitter acid analysis in hops faster and more reliable.<h4>How can you detect bitter acid profiles quickly, reliably, and more sustainably?</h4>For craft brewers and beer lovers alike, a refreshing experience is all about flavor.So how can you achieve the desired bitterness in your beer? The answer is not just about the recipe. Finding the right flavor profile starts with the bitter acids present in the starting hops material.<div><div>Hops (the heart of your favorite beer) are the source of the brew’s distinctive flavor tied to bitterness and aroma.At the molecular level, bitterness is driven by <a target="_blank" rel="noopener noreferrer" href="https://www.sciencedirect.com/science/article/pii/S0308814622016338">α- and β-bitter acids</a>, like humulones and lupulones, whose concentrations determine the final sensory profile of the beer (Figure 1).Accurately characterizing these compounds in each batch allows brewers to unlock the full potential of every variety of hops.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_How_Bitter_Acid_Analysis_Helps_Brewers_Better_Control_Beer_Flavors_2_6435757c03.jpeg" alt="Thermo Fisher Scientific: How Bitter Acid Analysis Helps Brewers Better Control Beer Flavors: Figure 1.

Here’s why.Manual SPE has a lot of manual steps. Extraction. Cartridge loading. Washing. Elution. And sometimes solvent exchange or reduction. All before your actual analysis begins. This labor-intensive workflow can take up to an hour and depends strongly on operator skillsets, making reproducibility a challenge for new hires.<h4>Online SPE analysis provides key benefits like:</h4><ul><li>Hands-off workflow free of cartridges, manifolds, or vacuum steps.</li><li>Column washing and re-equilibration occur in parallel with separation.</li><li>SPE step is complete in just two minutes.</li><li>Minimizes operator-dependent variability.</li><li>Uses less than 8 mL of solvent.</li></ul>Let’s explore what this technique looks like in practice.<h4>Online SPE for analyzing α- and β-bitter acids in hops standard solutions.</h4>Changing your sample preparation from manual to automated isn’t complicated. With the right tools you can fully integrate online SPE with your UHPLC system (Figure 2).<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_How_Bitter_Acid_Analysis_Helps_Brewers_Better_Control_Beer_Flavors_3_4fb14243b4.jpeg" alt="Thermo Fisher Scientific: How Bitter Acid Analysis Helps Brewers Better Control Beer Flavors: Figure 2.

UHPLC compatible columns with particle size ≤ 2 µm boost analysis with higher flow rate, thus shorter analysis time and solvent consumption.</div><div><h5>What’s the best workflow for hops analysis?</h5>A typical workflow for hop analysis consists of three main steps: extraction of the target compounds, clean-up of co-extracted matrix components, and instrumental analysis by HPLC or UHPLC. To keep this workflow efficient and reproducible, you should minimize manual handling and add in automation when possible. Integrating online SPE into your LC instrument allows sample clean-up to run automatically, reducing hands-on time, solvent use, and variability while delivering faster, more reliable results.</div></div><blockquote>Visit us on&nbsp;<a target="_blank" rel="noopener noreferrer" href="https://www.linkedin.com/showcase/72003132/admin/dashboard/">LinkedIn:</a>&nbsp;#UHPLC #Automation</blockquote></div></div>

The international standard ISO/IEC 17025 [1] clause 7.7.2 with regards to ensuring the validity of results, requires a laboratory to participate in proficiency testing (PT) and/or to participate in interlaboratory comparisons (ILCs) other than PT. However, no guidance as to what these other ILCs might be, or indeed how they might compare in relation to PT, is provided. This leaflet aims to outline other ILCs available, pointing out some of the limitations as compared to PT.&nbsp;There are three major types of ILCs in which a group of laboratories analyses identical portions from a homogeneous, stable test sample, with each type being characterized by its intended purpose [2,3]:<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_2_d9263807fb.jpg" alt="Eurachem: Interlaboratory comparisons other than proficiency testing" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_2_d9263807fb.jpg 245w," sizes="100vw" width="1507" height="607">A key point is that PT is an ILC that is designed to specifically evaluate the performance of participants, providing them with an infrastructure to monitor and assess the validity of their results. This is not the key purpose of the two other ILCs, and thus depending on their intended purpose they have a number of limitations that laboratories need to be aware of when using them rather than PT. Only proficiency testing should have been conducted in full compliance to the competency standard ISO/IEC 17043 [4].&nbsp;<h4>Evaluation of measurement procedure performance&nbsp;</h4>These ILCs, are designed to assess how a particular measurement procedure performs and whether it is fit for its intended purpose. These ILCs are often referred to as a ‘method performance study’ or a ‘collaborative study’ [2]. Some limitations of using such ILCs for monitoring laboratory performance as an alternative to PT are:&nbsp;<ul><li>All participants use the same measurement procedure i.e. the measurement procedure that is being validated. Unless the measurement procedure is being routinely used by the participating laboratory such an ILC will not assess the routine performance of the laboratory using their own routine measurement procedure. Nor does it enable them to compare their performance with other laboratories using alternative measurement procedures.&nbsp;</li><li>The measurement procedure is likely to be new, so participants may not have established stable procedures and quality control, so performance may not reflect routine use.&nbsp;</li><li>The report from such an ILC would not provide information on the performance of the participant, if the statistical model used makes the assumption that all laboratories perform with equal variability.</li><li>The design of the study may require the participants to assess multiple samples and/or to undertake multiple replicate analysis on the test materials. This may not be representative of the routine measurements or tests undertaken by the laboratory.&nbsp;</li><li>The conclusion of the ILC might be that the measurement procedure being assessed is not valid.&nbsp;</li></ul><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_3_a53ecd2f5d.jpg" alt="Eurachem: Interlaboratory comparisons other than proficiency testing" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Interlaboratory_comparisons_other_than_proficiency_testing_3_a53ecd2f5d.jpg 157w," sizes="100vw" width="570" height="566"><h4>Characterisation of candidate reference materials&nbsp;</h4>These are ILCs that assign a property value to a candidate reference material, usually with a stated measurement uncertainty. These are often referred to as a ‘material certification study’ [2]. Limitations of using such ILCs as an alternative to PT are:&nbsp;<ul><li>The analysis of the candidate reference material is likely to require additional care in exercising the routine measurement procedure, such as substantially more replication, and/or may require quite different reporting formats (e.g. all valid replicates instead of a mean result). Thus, such an ILC will not necessarily provide an evaluation of the performance of the laboratory based on the routine use of their measurement procedures.&nbsp;</li><li>The report from such an ILC may include the results from the participating laboratories but would not provide information on the performance of each laboratory.&nbsp;</li><li>Participating laboratories may be required to assess multiple samples and/or to undertake multiple replicate analysis on the candidate reference materials. Thus this may not be representative of the routine measurements or tests undertaken by the laboratory.&nbsp;</li></ul><h4>Other ILCs&nbsp;</h4>Some other ILCs, whilst not being conducted in full compliance of the requirements of ISO/IEC 17043, may be designed to evaluate participant performance. These would include small ILCs as defined by EA‑2/21 [5] or split sample ILCs i.e. where a portion of a single sample is sent to two or three laboratories. Whilst these ILCs are specifically designed to evaluate participant performance, they may not provide a comprehensive comparison that a PT might provide. In such cases the laboratory needs to evaluate carefully the competence of the organization managing the ILC and the suitability of the service externally provided (ISO/IEC 17025 clause 6.6).

Agilent Technologies: Things You May Not Know or May Have Forgotten

Things You May Not Know or May Have Forgotten

Build your HPLC chromatography knowledge.

In most HPLC separations there is a wanted interaction of the sample with a chromatography packing.
When doing GPC/SEC separations, that is not the case. GPC/SEC is a noninteractive technique that separates samples based on their size in solution and not on their chemistry. This presentation will cover the common questions that should be asked when developing a robust and reproducible GPC/SEC method.
Topics will include:
<ul>
<li>Sample type: protein vs polymer
</li>
<li>Solvent Selection and its importance
</li>
<li>Column Choices &amp; how to choose correctly
</li>
<li>Calibrants
</li>
<li>Detector &amp; Instrument Considerations
</li>
</ul>
As we discuss each topic area we’ll look at examples and provide valuable tips that can help you achieve long term reproducible and reliable results.
