Our yearly report on new products covers sample preparation instrumentation, supplies, and accessories. New sample preparation technologies introduced in the past year, while not necessarily disruptive, take giant leaps in that direction.

A bad connection between an LC column and the rest of the system can ruin a good separation. New technologies may improve the quality of these connections and the likelihood of establishing a good connection in the first place. Understanding the issues will help you choose the best option for you.

We present our annual review of new developments in the field of gas chromatography, which this year includes eight new GC and GC–MS laboratory benchtop systems as well as numerous new columns and accessories.

Good maintenance of the GC inlet can prevent a host of problems fromcompromising the quality of your results.

Integration is the heart of the chromatographic process and is subject to regulatory scrutiny. What should be done to control integration and interpretation of the chromatographic runs?

A novel automated ultratrace gas chromatography–mass spectrometry (GC–MS) method has been developed that quantitates the eight toxaphene Parlar congeners designated in U.S. Environmental Protection Agency Method 8276. This method, combined with an efficient extraction, cleanup, and fractionation technique, makes is possible to extend instrument detection limits to the low parts-per-trillion concentration level for these toxaphene Parlar congeners.

Cannabis products are frequently tested for potency, pesticides and fungicides, solvent residues, heavy metals, microbes, foreign organic matter, and moisture. The most common techniques used for these tests are high-performance liquid chromatography (HPLC), gas chromatography (GC), LC or GC with mass spectrometry detection, and inductively coupled plasma–MS.
