Method validation processes will need to be refined to better suit forensic laboratories.

An improved LC–MS/MS method that can rapidly detect fipronil, an insecticide harmful to human health, is presented here for chicken eggs, feed, and soil.

Intact mass analysis is becoming increasingly useful for characterizing biologics. We describe the current application of intact mass analysis, including quantitation, sequencing, and structural characterization.

We explore the aspects of sampling that are of highest importance in an analytical scheme. Devices and processes for obtaining appropriate samples outside of the laboratory are presented.

Gas chromatographers may not have the latest equipment they need. Here, we give a list of tools and consumables that can help make workflows more efficient, detection limits lower, and GC instruments cleaner.

What leads to an asymmetric peak shape? Physiochemical phenomena can help chromatographers identify whether the cause of asymmetry has a chemical or physical origin.
