Here are the top five articles that the editors of LCGC International published this week.

Adopted 35 years ago, the Montreal Protocol is an international treaty designed to protect the ozone layer. It addresses ozone depletion caused by industrial chemicals and remains a landmark environmental agreement in the phasing out and ban of the production and consumption of ozone-depleting substances (ODSs).

A study has used gas chromatography coupled to a time-of-flight mass spectrometer to build an electron ionization mass spectra database of more than 250 chemicals classified as either volatile or semi-volatile compounds. An additional, confirmatory layer of liquid chromatography–mass spectrometry analysis was subsequently performed.

Element Materials Technology introduced its Rapid Response Pharmaceutical Testing Service, providing expedited testing and focusing on various requirements including active ingredients and final drug products, extractables and leachables, degradation production, and elemental impurities.

A study has proposed targeted methods, developed using gas chromatography coupled to tandem mass spectrometry, to measure human plasma protein binding and hepatocyte clearance in 73 per- and polyfluoroalkyl substances, or PFAS.

Limited toxicokinetic and toxicologic information is available about a diverse set of per- and polyfluoroalkyl substances (PFAS), but methods based on gas chromatography–tandem mass spectrometry (GC–MS/MS) can help unravel some of the mystery.

The company’s new service will provide expedited testing to customer around the world.

This week, LCGC International published a variety of articles on the hottest topics in chromatography and beyond. Below, we’ve highlighted some of the most popular articles, according to our readers. Happy reading!

In this edition of “Inside the Laboratory,” Kevin Schug, PhD, a full professor of chemistry at the University of Texas at Arlington, discusses his laboratory’s group work in environmental monitoring around water and soil quality near oil and gas extraction, using techniques such as liquid chromatography (LC), gas chromatography (GC), supercritical fluid chromatography (SFC), and coupling these techniques with mass spectrometry (MS).

Scientists investigated using this method to measure volatile organic compounds in the breath of patients with chronic kidney disease.

Researchers from Austria, Greece, and Italy conducted a study to analyze volatile organic compounds (VOCs) present in Irish and Scotch whiskys using solid-phase microextraction (SPME) Arrow with comprehensive two-dimensional gas chromatography coupled to mass spectrometry (GC×GC–MS) to examine the organoleptic characteristics that influence the taste of spirits.

A recent study from the Cantonal Laboratory Zürich examined using micro solid-phase extraction for pesticide analysis.

A recent study explores the use of liquid–liquid extraction (LLE) and gas chromatography–mass spectrometry (GC–MS) to identify the compounds found in extractives of Alaska Yellow Cedar trees.

A group of Taiwanese scientists have recently created a new method for assessing food quality and detecting histamine in wine samples.
