In this issue – I hope to outline some 'small bolts' that are commonly ignored in everyday chromatography and mass spectrometry - instrument settings that I have to come call 'lock and leave' parameters. We can generate data without changing them or paying them any attention, but how much better could our data be if we bothered to optimise them.

The Kendrick mass defect combined with liquid chromatography quadrupole time-of-flight mass spectrometry (LC–qTOF-MS) can offer a variety of benefits to analysts investigating groundwater contamination. LCGC spoke to Thomas Borch from Colorado State University in Colorado, USA, about his work in this area to find out more.

Scientists at the Norwegian Defence Research Establishment (Kjeller, Norway) are working in collaboration with the University of Oslo (Oslo, Norway) to develop new methods to detect the illicit use of nerve agents. In a recent study published in the journal Analytical Chemistry, the team presented a novel method for the quantification of nerve agent metabolites in human serum and urine by combining salting-out assisted liquid–liquid extraction (SALLE) and on-line solid-phase extraction–liquid chromatography–tandem mass spectrometry (SPE–LC–MS–MS).

A new study published in the Journal of Chromatography A presents metabolite profiling of tea (Camella sinensis) harvested from the Bulang Mountains in Yunnan, China, using multidimensional gas chromatography–mass spectrometry (GC×GC–MS) to determine the impact of seasonal changes.

A new study published in the journal Analytical Chemistry presents a drug metabolism strategy based on microsome mesoporous organosilica nanoreactors coupled with high performance liquid chromatography–mass spectrometry (HPLC–MS) to screen for potential drug toxicity.
