USP chapter can help ensure data integrity of a chromatography data system. Here’s how.

By optimizing and fully automating the bubble-in-drop microextraction process, this sample preparation technique, combined with gas chromatography–mass spectrometry (GC–MS) analysis, provides high precision and good figures of merit, as shown for selected organochlorine pesticides in the analysis of tap water and reservoir water samples.

Sometimes, the conditions specified in legacy liquid chromatography (LC) methods seem like they come from a different planet. This month, we look at which conditions to keep, and which ones to let go of.

Highly repeatable fragmentation of the compounds into the ion source is one of the major advantages of using gas chromatography coupled with electron ionization mass spectrometry (GC–EI-MS) for the analysis of volatile and semivolatile compounds. The generation of intense and diagnostic fragmentation when the ionization is performed at 70 eV has been used for the creation of many established databases-enabling the analyte identification process.
