An improved liquid chromatography tandem mass spectrometry (LC–MS–MS) method for the screening and confirmation of clenbuterol in human urine in sports doping applications was developed and validated.

Written procedures used by trained staff are the basis for all quality systems but there are many ways of writing a procedure. Are you getting it write?

Quinine- and quinidine-derived anion-exchanger chiral stationary phases have proven to be versatile in enantiomer separation of acidic compounds in HPLC. In this article, the authors demonstrate their performance in specific HPLC applications involving enantiomer resolution and topoisomer separation.

In this month's instament, John Hinshaw addresses a number of frequently asked questions about gases and their delivery to a gas chromatography instrument.

How can we tell if a liquid chromatography method is working properly? How can a compendial method be adjusted to speed up the run time?
