This workflow confirms and quantifies 31 drugs of abuse in oral fluid (including THC) in a 4.5‑minute LC run on the <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/1149">Thermo Scientific Stellar mass spectrometer</a> using full scan + targeted MS2 (tMS2) with both HCD and CID fragmentation. With 1 µL injection and 0.1% formic acid in water/methanol mobile phases, the method supports ~13 samples/hour (up to ~320/day continuous operation) while maintaining confirmation performance via ion ratios.<blockquote><h5>Method at a glance</h5><ul><li>What matrix is tested? Oral fluid</li><li>How many drugs? 31 drugs of abuse (panel includes THC)</li><li>Run time? 4.5 minutes</li><li>Throughput? ~13 samples/hour → up to ~320 samples/day (24‑hour operation)</li><li>Injection volume? 1 µL</li><li>Mobile phases? 0.1% formic acid in water (A) and 0.1% formic acid in methanol (B)</li><li>MS acquisition?

The challenge is building a method that’s simultaneously:<ul><li>Broad enough for today’s drug panels</li><li>Sensitive enough to reach required cutoffs</li><li>Fast enough to keep sample queues under control</li><li>Confirmation‑ready (consistent product ions and ion ratios)</li></ul>A 4.5‑minute method is a practical lever here: compress runtime, raise throughput, and still keep confirmation quality by optimizing MS/MS conditions per compound.<h3>The LC method</h3>A short, efficient separation is the foundation of the workflow:<ul><li>UHPLC system: <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/744">Thermo Scientific Vanquish Horizon UHPLC</a></li><li>Column: <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/424">Thermo Scientific Accucore Biphenyl</a>, 50 × 2.1 mm, 2.6 µm</li><li>Mobile phase A: 0.1% formic acid in water</li><li>Mobile phase B: 0.1% formic acid in methanol</li><li>Injection volume: 1 µL</li><li>Gradient runtime: 4.5 minutes</li></ul><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_4_5_Minute_Oral_Fluid_LC_MS_Method_to_Detect_31_Drugs_of_Abuse_Using_Stellar_MS_fd3f3e8ea4.jpg" alt="Thermo Fisher Scientific: 4.5-Minute Oral Fluid LC MS Method to Detect 31 Drugs of Abuse Using Stellar MS: Figure 1: Thermo Scientific Vanquish Horizon UHPLC system." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_4_5_Minute_Oral_Fluid_LC_MS_Method_to_Detect_31_Drugs_of_Abuse_Using_Stellar_MS_fd3f3e8ea4.jpg 120w," sizes="100vw" width="747" height="969"><h3>The MS method (Full scan + targeted MS2 with HCD + CID)</h3><h5>Acquisition approach</h5>This method uses a “two‑layer” strategy for quantitation + confirmation:<ol><li>Full scan (broad coverage, context, quantitative support)</li><li>Targeted MS2 (tMS2) (confirmation‑focused product ions, ion ratios)</li></ol><h5>The key differentiator: HCD and CID in one targeted list</h5>Instead of forcing every analyte into a single fragmentation style, the method uses both:<ul><li>HCD (beam‑type fragmentation)</li><li>CID (resonance‑type fragmentation)</li></ul><h5>Why that improves method development:</h5>Drugs of abuse span multiple chemistries. A single collision approach often works “okay” for most compounds—but one or two analytes can become persistent problems (weak qualifiers, unstable ion ratios, excess noise). Having both HCD and CID available in one method lets you optimize per compound and move faster.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_4_5_Minute_Oral_Fluid_LC_MS_Method_to_Detect_31_Drugs_of_Abuse_Using_Stellar_MS_3_e4a95651a2.jpg" alt="Thermo Fisher Scientific: 4.5-Minute Oral Fluid LC MS Method to Detect 31 Drugs of Abuse Using Stellar MS: Figure 2: Thermo Scientific Stellar mass spectrometer." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_4_5_Minute_Oral_Fluid_LC_MS_Method_to_Detect_31_Drugs_of_Abuse_Using_Stellar_MS_3_e4a95651a2.jpg 245w," sizes="100vw" width="645" height="377"><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_4_5_Minute_Oral_Fluid_LC_MS_Method_to_Detect_31_Drugs_of_Abuse_Using_Stellar_MS_5_88276eec6a.jpg" alt="Thermo Fisher Scientific: 4.5-Minute Oral Fluid LC MS Method to Detect 31 Drugs of Abuse Using Stellar MS: Figure 3: Full scan &amp; targeted MS2 methods, HCD and collision energies used." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_4_5_Minute_Oral_Fluid_LC_MS_Method_to_Detect_31_Drugs_of_Abuse_Using_Stellar_MS_5_88276eec6a.jpg 245w," sizes="100vw" width="768" height="279"><h3>Why CID + HCD flexibility improves confirmation</h3>In this workflow, HCD performed well for most compounds. But for buprenorphine, HCD produced one dominant product ion with additional low m/z noise and noticeable residual precursor. Using CID generated two high‑intensity product ions and delivered consistent ion ratios across the calibration range.When your confirmation hinges on stable ion ratios, the ability to switch fragmentation mode (not just collision energy) is a method‑development advantage—especially for “problem analytes.”<h3>Controllable ionization</h3>Oral fluid methods often deal with limited sample volume and matrix effects. This workflow pairs low injection volume with ionization control using the Thermo Scientific OptaMax Plus HESI source.<ul><li>The OptaMax Plus HESI source supports high probe temperature capability (up to 650 °C).</li><li>In this study, a vaporizer temperature of 500 °C was used to help achieve sensitivity and improve relative peak areas across drugs of abuse.</li></ul>Why this matters: If you’re injecting only 1 µL, ionization stability and efficiency can be the difference between “meets cutoff” and “misses at LOQ.”<h3>Sample preparation</h3>Oral fluid panels become more challenging when THC is included because most drugs of abuse are basic, while THC is largely neutral, and that can stress extraction chemistry.In this workflow, oral fluid calibrators and samples were extracted using a mixed‑mode approach designed to recover THC alongside other drugs:<ul><li>Calibrators prepared across eight levels (broad dynamic range)</li><li>Extraction performed using mixed‑mode chemistry tips (SCX/WAX) in a dispersive SPE‑style workflow</li><li>Steps automated on a liquid handling platform to support high‑throughput consistency</li><li>Samples dried and reconstituted prior to LC‑MS analysis</li><li>Only 1 µL injected per run</li></ul>Even if your lab uses different automation or consumables, the method structure (fast LC + full scan + targeted MS2 with dual fragmentation) transfers well.<blockquote><h5>Throughput math</h5><ul><li>4.5 minutes per injection → 60 / 4.5 = 13.3 injections/hour</li><li>That’s ~13 samples/hour in typical phrasing</li><li>Over 24 hours: 13.3 × 24 = ~320 samples/day (continuous operation)</li></ul>If you run a single shift, just scale accordingly (e.g., ~106/day for an 8‑hour shift, excluding QC and overhead).</blockquote><h3>Performance summary</h3><h5>Sensitivity and linearity</h5><ul><li>Linearity from LOQs as low as 0.25 ng/mL up to 1,000 ng/mL (panel-dependent)</li><li>For THC specifically: LOQ at 1 ng/mL, with a dynamic range extending to 1,000 ng/mL in this evaluation</li><li>Across the panel, LOQs were reported as lower than recommended confirmation cutoffs referenced in SAMHSA guidance and NSC Tier 1 cutoffs (study-specific outcome)</li></ul><h5>Confirmation via ion ratios</h5><ul><li>Ion ratios evaluated using ±20% tolerance (typical confirmatory acceptance framework)</li><li>The workflow produced consistent ion ratios across calibrator levels for the full panel in this evaluation</li></ul><h5>Case sample comparison (real-world relevance)</h5>When compared against a validated triple quadrupole method for case study samples, the Stellar MS workflow:<ul><li>Confirmed the positive hits observed by the reference method</li><li>Reported a few additional positives for select analytes, attributed to lower LOQs</li><li>Highlighted an operational efficiency point: 1 µL injection in this method versus 20 µL injection in the compared method</li></ul><h3>FAQ</h3><div><div><ol><li>How long does the LC‑MS run take for the 31‑drug oral fluid panel? 4.5 minutes per injection using a short UHPLC gradient. &nbsp;</li><li>How many drugs of abuse can Stellar MS detect in this workflow? 31 drugs of abuse, including THC, using full scan + targeted MS2. &nbsp;</li><li>What MS/MS approach is used? A combined strategy: full scan plus targeted MS2 (tMS2) for confirmation. &nbsp;</li><li>Why use both HCD and CID? Because some analytes fragment better—and produce more stable confirmation ions/ion ratios—under one mode versus the other. Using both increases flexibility and speeds method optimization. &nbsp;</li><li>What injection volume is used? 1 µL of extracted sample. &nbsp;</li><li>What mobile phases are used? 0.1% formic acid in water (A) and 0.1% formic acid in methanol (B). &nbsp;</li><li>How many samples can you run per day? At 4.5 minutes/injection, throughput is ~13 samples/hour or up to ~320/day with continuous operation (actual throughput depends on QC and scheduling).</li></ol></div></div><h3>What makes this workflow “easy” to develop on Stellar MS</h3>Here’s the short list of features that directly reduce method‑development friction:<ul><li>HCD or CID in one method → optimize per compound, not compromise</li><li>Fast MS2 acquisition speeds (up to 140 Hz for MS2) → more data points across narrow peaks</li><li>Fast polarity switching (true 5 ms) → supports mixed panels efficiently</li><li>Adaptive RT (real‑time retention time window adjustment) → helps reduce reinjections when retention times drift (e.g., column aging) and supports method transfer from longer to shorter gradients</li><li>OptaMax Plus HESI source control → supports sensitivity at low injection volumes</li></ul>If you’re building a fast oral fluid confirmation workflow—or updating an existing DOA panel—this 4.5‑minute method shows how Stellar MS can combine speed, confirmation-ready MS2, and fragmentation flexibility (HCD + CID) in a single targeted workflow.

ECOM ECP201LG Gradient Preparative Pump 1000 mL/min

An innovative, powerful, and cost-effective unit for preparative LC separations with high pressure. 4 low pressure gradient valves, flow up to 1000 mL/min. 

<div style="display:block;" aria-labelledby="tab_item-0">The ECP201L Preparative Pump is an innovative, powerful, and cost-effective unit for preparative liquid chromatography where high pressure is needed. The pump with 4 low-pressure valves delivers a flow rate of up to 1000 mL/min at a very high output pressure of up to 15 MPa (2176 psi).<h3>Main features and benefits</h3><h4>Durability</h4>The pump is constructed for high pressure and flow rates. This makes it suitable for day-to-day long-term use in production<h4>Wide application possibilities</h4>The unit is used for pharmaceutical separations and plant extract purification, such as cannabinoids, peptides, and oligonucleotides. Also, it has much wider use in other chemical production, such as dosing into chemical reactors, and in various laboratory uses. Another advantage is the usability of the same device for separation method development.<h4>Smart controls and diagnostics</h4>It is easy to operate, especially with ECOMAC and Clarity software. This makes unit management powerful and convenient. The basic version of the ECOMAC software is available free of charge. It is also used for service and diagnostics.<h4>Other useful features</h4><ul><li>A new learning algorithm for pulsation suppression</li><li>A leakage sensor</li><li>A seal wash kit for longer piston seal life</li><li>Also available in configurations made of certified bio-inert materials</li></ul><h3>Parameters</h3><ul><li>Flow rate: 1 – 1000 ml/min</li><li>Maximum operating pressure in the pump: 15 MPa up to 1000 ml/min</li><li>Flow rate setting: 1 ml/min steps</li><li>Repeatability of flow rate adjusting: ± 1 %</li><li>Accuracy of flow rate setting: ± 2 %</li><li>Wetted materials in the pump: stainless steel, PEEK, TefzelTM, Kalrez®, ceramic, seals GFP (PTFE) by default or UHMW-PE on request</li><li>Control: RS232, Ethernet(LAN), USB</li><li>Output capillary outer diameter: 1/8 "</li><li>Input tubing outer diameter: 3/8 ”</li><li>Number of gradient valves*: 4 (A,B,C,D)</li><li>Orifice: 5 mm</li><li>Fluid temperature: 5 - 90°C</li><li>Connecting thread: 5/8" - 18 UNF</li><li>Power supply: 100 - 240 V AC</li><li>Power input: 500 VA</li><li>Weight of the complete set: 30 kg (66.14 lb)</li><li>Dimensions (w x h x d) of the complete set: 340 x 170 x 640 mm (13.4 x 6.7 x 25.2 in)</li></ul></div>

ECP2050 Preparative Pump

Preparative HPLC pump with flow-rate ranges of 0.001 to 50 ml/min. 

<div style="display:block;" aria-labelledby="tab_item-0">This pump works as an isocratic pump 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. The pumps can operate in two modes, i.e. using constant pressure or the newly added option of constant flow rate. New material versions have been added-in beyond to stainless steel A316L, also Hastelloy, titanium and PEEK for biocompatible applications.<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 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. You can order the pumps with UHMW-PE seals, which are considered the optimal recommended choice.<h4>Software support</h4>The pumps are supported by ECOMAC and Clarity software.<h3>Main features and benefits</h3><ul><li>All models include a display and keyboard for manual control</li><li>Precise low-pressure gradient mixing (when connected with a gradient module)</li><li>Very good durability and reliability with proper maintenance</li><li>Extended number of wetted material versions – not only stainless steel but also Hastelloy, titanium and PEEK for biocompatible applications</li><li>Piston back-washing function for work with buffered or aggressive mobile phases</li><li>New learning algorithm for pulsation suppression</li><li>Integrated leakage sensor</li><li>Heating unit for pump heads available</li><li>Custom pump modifications of request</li></ul>This pump is equipped with the Pressure Compensation Learning algorithm.

ECOM Separchrom PC01-HPLC Industrial Preparative Columns with Axial Compression

Separchrom PC01 ECOM industrial preparative columns correspond to the highest requirements of preparative liquid chromatography. They are designed to be used in a mode of axial compression with a moving input piston. 

<div style="display:block;" aria-labelledby="tab_item-0">HPLC Columns for prep chromatography. High performance columns with axial compression.Separchrom PC01 ECOM columns correspond to the highest requirements of preparative liquid chromatography. They are designed to be used in a mode of axial compression with a moving input piston. In the original design, they are equipped with identical pistons on input and output (biaxial compression as an option). In the ECOM Separchrom PC FE modification, they have a fixed end plate on the output instead of the piston. Pistons and plates are equipped with frits. A liquid distributing system is installed under each frit. The design guarantees perfect piston flow, high efficiency even for high injection volume, and simple accessibility of frits for cleaning. Columns can be packed by dynamic slurry method or by sedimentation or with sorbent in a dry state.SEPARCHROM PC 01 ECOM columns are made of stainless steel AISI 316L (tube inner surface is polished to reach Ra &lt; 0.3 µm) with stainless steel pistons and UHMWPE (PTFE on the request) sealing rings. The stroke of the main piston is proportional to the used hydraulic cylinder or flange bolt length. Pistons are sectional; the frit (sintered mesh disc 3 µm pore size, 5 mm thickness) with the frit ring can be removed. The output plate in the FE version is made of UHMWPE, frit is fixed with a simple frit ring. Column flanges are not welded, but screwed onto the column tube. No temperature increase during manufacturing means no change in steel properties. The column stand made of stainless steel profiles is included for columns over 100 mm I.D.Hydraulic cylinders fitted on the upper flange are offered with manual oil pumps as well as with fully automated electric motor-driven devices for column packing/unpacking procedures.<h3>Accessories</h3>Columns are offered with a broad scale of accessories such as filling adapters, slurry mixing vessels, slurry transporting pumps, etc.<h3>COLUMN CONFIGURATION EXAMPLES</h3>Columns are custom-made, do not hesitate to ask for any other sizes within the possible ranges<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_1_1795482301.jpg" alt="ECOM: Separchrom PC01-HPLC Column - available configuration - part 1" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_1_1795482301.jpg 236w," sizes="100vw" width="1440" height="952"><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_2_6d3198af67.jpg" alt="ECOM: Separchrom PC01-HPLC Column - available configuration - part 2" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_2_6d3198af67.jpg 239w," sizes="100vw" width="1442" height="942"><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_3_9fd77a1054.jpg" alt="ECOM: Separchrom PC01-HPLC Column - available configuration - part 3" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_ECOM_Separchrom_PC_01_HPLC_Column_available_configuration_part_3_9fd77a1054.jpg 245w," sizes="100vw" width="1435" height="315"></div>
