A two-dimensional gas chromatography-time-of-flight mass spectrometry method detects legacy pesticides and PCBs below guideline levels.

Gel Permeation Chromatography (GPC) is a form of size exclusion chromatography which can be used to 'clean' complex mixtures of large, interfering molecules from samples further used for analytical ...

As mass spectrometry (MS) workflows become faster and more sensitive, one persistent challenge has become increasingly clear: sample preparation is now the primary bottleneck limiting throughput and ...

Precise temperature control is essential for MS to work optimally and provide accurate GC-MS results. Recirculating chillers from PolyScience are the ideal solution for cooling the MS component of ...
