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.
