Ever-tightening environmental regulations have led to increased sensitivity requirements from commonly utilized analytical techniques such as GC-MS. Additionally, there is a need to reduce the injected volume of samples in order to minimize matrix effects. 

APGC is a technique that operates at atmospheric pressure and uses a soft ionization process which can be used as precursor ions in MRM experiments for multi-residue GC-MS/MS analysis. APGC provides access to ultra-trace quantification, comprehensive qualitative MS & MS/MS, and high-resolution, ion-mobility separations. Application areas include the detection of multi-residue pesticides, dioxins, furans, POPs, and PCBs.
