Application Note: Using a Novel Atmospheric Pressure GC Source Coupled to High-Resolution TOF-MS to Analyze Environmental Samples
6 Mar 2015

A new gas chromatography atmospheric pressure chemical ionization (GC-APCI) source coupled to a high-resolution QTOF-MS was used for the GC/MS analysis of polycyclic aromatic hydrocarbons (PAH), pesticide and explosive standards as well as soil, sediment and sludge samples of environmental origin. Compared to an earlier GC-APCI design, the source demonstrated improved GC/MS performance in terms of reproducibility and analytical working range.
