Extraction methods to help labs establish potency testing methods that will provide the best return on investment without sacrificing data quality.

Semivolatiles methods are essential parts of environmental testing programs, yet they can be difficult for labs to run efficiently.

Poly- and perfluoroalkyl substances are rapidly emerging as some of the most important environmental contaminants to monitor around the world

Here, we’ll examine the properties that are important to consider when choosing an LC column for PFAS analysis.

From airplane and runway deicing to hydraulic fracturing operations, glycols are common chemicals used in industry

Currently, methods that allow the desired combined analysis of ultrashort-chain PFAS with alternative and legacy PFAS are very rare.

Raptor™ C18 SPP 5 μm core-shell silica particle columns offer excellent resolution for fluorochemicals with short total cycle times. For even faster analysis, 2.7 μm core-shell particles are available.

The intent of this application was to develop an LC-MS/MS method for the analysis of thyroid hormones at the free form levels using the highly efficient and selective Raptor™ Biphenyl LC column.

As the demand for testing of pain management drugs increases, many laboratories are turning to LC-MS/MS for its increased speed, sensitivity, and specificity. The methods shown here use a Raptor™ Biphenyl column because it provides fast, accurate analysis of 231 drugs and drug metabolites.

Chromatographic conditions were developed for a fast GC-MS glycol ether analysis on the Rxi®-1301Sil MS column.

The new Pro EZLC chromatogram modeler is an easy-to-use yet powerful tool that cuts LC method development time and cost dramatically.

Specifically for semivolatiles (SVOC) analysis, Restek’s new Rxi-SVOCms columns mean consistent performance that will keep calibrations passing longer

Leverage Your MS Vacuum to Significantly Speed Up Analyses

ILSP is an ideal sample prep technique for food safety labs seeking to spend less time and money per LC-MS/MS sample without sacrificing performance.

Restek’s new nine-component cannabinoid mix streamlines cannabinoid analyses, combining nine compounds into one

Restek’s Terpenes MegaMix standards are certified reference materials (CRMs), manufactured and QC-tested in our ISO-accredited labs

Restek’s new Raptor Polar X column lets you easily analyze acidic, basic, and neutral polar compounds

Analyzing polar compounds using liquid chromatography has historically been a challenge.

Pro EZLC method translation software makes it quick and easy to scale down an existing LC method to a smaller column format

Restek’s electronic leak detector lets you pinpoint small gas leaks quickly and accurately before they cause bigger problems.
