QuEChERS has been updated to suit modern instrumentation. Now also “efficient and robust,” QuEChERSER is a “mega-method” that covers a wider polarity range.

QuEChERS has recently been updated to QuEChERSER (“more than QuEChERS” or also “efficient and robust”) to better take advantage of the features provided by modern MS-based detection tools.

Low-pressure gas chromatography (LPGC)–MS should be the first option in many GC–MS applications to provide fast, sensitive, and robust analyses; and the installation, instrumentation, and implementation of LPGC is possible in any GC–MS system.

In this extended special feature to celebrate the 30th anniversary edition of LCGC Europe, leading figures from the separation science community explore contemporary trends in separation science and identify possible future developments. We asked key opinion leaders in the field to discuss the current state of the art in gas chromatography instruments.

In this study, an empirical assessment of summation integration (using the lowest baseline point in user-defined tR windows) was conducted involving 490 low-pressure GC–MS/MS analyses of 70 pesticides in 10 common fruits and vegetables over the course of 10 days.
