The porous graphitized carbon (PGC) columns typically used for acrylamide analysis by method EN 16618:2015 provide adequate retention of acrylamide and sufficient separation from matrix components, but they are subject to long run times and short column lifetimes. Switching to an Allure Acrylamide LC column is a better alternative: an Allure Acrylamide column used with a deuterated internal standard provides faster total analysis times and meets system suitability requirements longer.
Allure Acrylamide columns meet the EN method 1.7-minute retention time requirement with good separation from matrix components and a much shorter equilibration time. A per analysis savings of 2.5 minutes allows more samples to be analyzed per shift, significantly increasing lab output. In addition to faster run times, testing showed that the Allure Acrylamide column passed the 1.7-minute system suitability requirement for over twice as many injections as a typical PGC column.
Developed to withstand 100% aqueous mobile phases and elute coextracted matrix components rather than strongly retaining them, Restek Allure Acrylamide guard and analytical columns deliver the same robust performance injection to injection and column to column, making them a more reliable choice for acrylamide analysis, even in difficult food matrices like potato chips or coffee.
Cannabicyclol (CBL) is formed through the photodegradation of cannabichromene (CBC). Levels are typically quite low, and the medicinal benefits of CBL are still being researched, but quantifying this compound in cannabis samples is crucial for obtaining a more-complete cannabinoids profile. Restek has just released a new CBL certified reference material (CRM) to further aid labs in the comprehensive characterization of cannabis: www.restek.com/catalog/view/54615
Restek’s new CBL standard is ideal for creating multipoint (5-point minimum suggested) calibration curves for LC analysis. With verified composition and stability, this prepared stock product eliminates the need for in-house standards preparation for greater convenience and lower labor requirements. As a U.S. DEA-exempted formulation, no additional customer permits or licensing are required to purchase within the U.S., and because it’s manufactured and QC tested in Restek’s ISO-accredited labs, this new CBL standard qualifies as a certified reference material (CRM) that satisfies your ISO requirements.

With best-in-class thermal stability, new Rxi-65TG columns from Restek are the top choice for accurate, reliable analysis of triglycerides (acylglycerols) in edible oils. Novel chemistry and cutting-edge manufacturing allow Rxi-65TG columns to outperform leading competitor columns and produce less bleed at a higher maximum temperature (370 °C) than competitor columns produce at their lower maximum temperature (360 °C). Less interference from column bleed means more accurate and sensitive detection of edible oil triglycerides—and more certainty in the results you report. In addition, higher temperature stability means consistent performance and longer column lifetimes with fewer column changes. Food testing labs will benefit from the reproducible retention times, robust inertness, stable baselines, and consistent column-to-column performance provided by low-bleed Rxi-65TG columns.
The harsh environment inside an MS source takes its toll on ESI electrodes, and once they corrode, sensitivity drops, runs fail, and productivity halts while the instrument is offline for maintenance. To help labs overcome this obstacle, Restek has developed the Long-Life ESI electrode for Sciex Turbo V sources, which is more rugged than original equipment manufacturer (OEM) electrodes. Testing shows that Long-Life ESI electrodes provide equivalent LC-MS/MS performance to OEM electrodes over significantly longer lifetimes. Because they perform the same and are less susceptible to corrosive conditions in the MS source, Restek Long-Life ESI electrodes ensure more instrument uptime for sample analysis and are a particularly good choice for high-throughput laboratories.

Cannabis strains with high levels of cannabidiol (CBD) typically have higher levels of cannabidivarin (CBDV) as well, but accurate quantitation of both compounds for potency and strain ID is a must, especially as interest in using CBDV as an anticonvulsant and anti-nausea treatment continues to rise. Restek now offers a stand-alone CBDV reference standard—in addition to CBD and a host of other compounds—to help labs with the comprehensive analysis of cannabis products.
Restek’s CBDV standard is ideal for creating multipoint (5-point minimum suggested) calibration curves for LC-MS/MS. With verified composition and stability, this prepared stock product eliminates the need for in-house standards preparation for greater convenience and lower labor requirements. As a U.S. DEA-exempted formulation, no additional customer permits or licensing are required to purchase within the U.S., and because it’s manufactured and QC tested in Restek’s ISO-accredited labs, this new CBDV standard qualifies as a certified reference material (CRM) that satisfies your ISO requirements.

New and improved, Restek’s electronic leak detector lets you pinpoint small gas leaks quickly and accurately before they cause bigger problems. Now, there’s no more waiting for a full charge—the unit can be operated during charging or used up to 12 hours between charges. This compact, handheld instrument detects a broad range of laboratory gases and indicates leak severity with both an LED display and audible tone. In addition, it comes with a flexible charging kit that includes both a universal AC power adaptor and a USB charging cable so you can charge anywhere, anytime. Using a Restek electronic leak detector to ensure all critical seals in the GC system are leak free is an easy way to prevent costly downtime, waste, and damage.
Restek first launched solid phase microextraction (SPME) automated sample preparation fibers to reduce sample handling and solvent consumption in many industries, such as environmental, food, and clinical. Soon after came rugged Restek PAL SPME Arrows, a revolution in microextraction that combines exceptional robustness with faster extraction times and trace-level sensitivity. Now, both fiber and Arrow lines are being expanded, including the addition of a sought-after triple-phase offering.
Of significant interest to many analysts, new triple-phase SPME fibers and Arrows provide exceptional versatility. This divinylbenzene (DVB)/carbon wide range (WR)/polydimethylsiloxane (PDMS) combination can be used for quick and efficient extraction of a wide range of both volatiles and semivolatiles, and it is an excellent choice for decision-making during method development because it combines the characteristics of three popular phases.

Low-level detection of carbon monoxide (CO) and carbon dioxide (CO2) is critical for many applications. Restek’s methanizer (CH4izer) allows ppb-level determination of CO and CO2 using a cost-effective FID instead of more expensive instrumentation. Up until now, the methanizer was only available for Agilent GCs, but Restek has just released a version of the methanizer for Thermo TRACE 1300/1310 GCs that features the same benefits to your lab as the original model.
The methanizer is factory set to 380 °C to ensure efficient and complete conversion of CO and CO2 to CH4, but the operator can easily adjust the temperature as desired with the touch of a button. This unit controls temperatures precisely and reliably to within ± 1 °C of the defined set point and the actual temperature is shown in real time on an easy-to-read display. The Restek methanizer is less cumbersome than other models and is designed for easy installation and fast catalyst tube replacement, so you spend more time analyzing samples and less time on maintenance.
Whether you run an Agilent or a Thermo TRACE 1300/1310, the methanizer you need is now available at
