High Sensitive MID Detection Method for Toxaphenes by High Resolution GC/MS

In this application a programmable temperature injector (PTV) was used with additional surge pressure for an accelerated sample vapor transfer to the analytical column. The analysis of toxaphenes is very challenging, not limited to the almost impossible chromatographic separation of the vast amount of isomers, the injection technique as well as the ionization performance have a great influence over reproducibility, linearity and sensitivity. Toxaphenes are included in the Annex A of the Stockholm Convention to protect human health and the environment from persistent organic pollutants (POPs). The international community has called for urgent global actions to reduce and eliminate releases of these listed chemicals including toxaphenes.
