It was found to effectively reduce background without significantly reducing recovery of lipophilic pesticides such as organochlorines and some pyrethroids. GC-MS full-scan data indicated Z-Sep+ was found to provide better cleanup in the form of reduced background than PSA/C18, and less interference in the GC-MS/SIM analysis of the target pesticides ...

Gas Chromatography- mass spectrometry (GC-MS) is a powerful tool used in forensic chemistry for the identification of the complex mixtures often encountered by forensic chemists. In GC analysis, compounds are separated from a mix and eluted from a column based on the structure’s affinity for the stationary phase. The elution is measured by retention time, and while the retention time of a given compound in a GC method can provide clues to ...

Easily Label Autosampler Vials and Streamline Chromatography. It’s not unusual for an analytical chemistry lab to run between 250 and 1,000 autosampler vials a day. As a result, vial labeling becomes so difficult and time consuming that many analytical chemistry labs turn to unreliable hand-written vial labels for analytical chemistry or run autosampler vials without any label at all. ...
