AnalysisOPPesticides byGC/MS
Polymers designed for selective detectors, like theNPDor FPD,
mustmaximize resolutionbetween analytes for identification and
quantitation.
Due to the high selectivity for themodeled
compounds, these columns are also a good choice forGC/MS
analysis.
AlthoughMSdetectors canbe used for resolving
compounds that chromatographically coelute, it is best tominimize
coelutions.
TheRtx-OPPesticides2 column is optimized for resolution of all
53OPPesticides and ismadewith a lowbleedpolymer.
This
makes the column an excellent choice forGC/MS analysis of
organophosphorus pesticides.
The following chromatogramshows
an analysis time of <21minutes andonly2 pairs of coeluting
compounds.
These coeluting compounds have differentmass
spectra, allowing themtobe identified and quantitated.
