Qualitative Analysis of Impurities and Additives in Insecticide by GC/Q-TOF
The demand for comprehensive qualitative analysis by GC/MS is increasing in all fields. In general, EI mass spectrum libraries are used for qualitative analyses by GC/MS, but there are many compounds that do not provide a hit in commercially available libraries. GC/Q-TOF, with high resolution and MS/MS capabilities, has excellent qualitative abilities for such unknown compounds by utilizing positive ion chemical ionization (PICI). An ideal PICI trait is that cation adducts can appear and be identified in many compounds. In this study, a mixed gas of methylamine (MA) and methane was evaluated as PICI reagent gas. The method was applied to commercially available insecticide, and many qualitative compound aspects could be obtained.
