Summary
–
TheRtx-OPPesticides andRtx-OPPesticides2 columns are the
optimal dual columnpair forUSEPA8141A.
–
TheRtx-OPPesticides2 columnprovides the best separationof
organophosphorus pesticides byGC/MSdue to the lowbleedof
this phase and separation of compoundswith similar spectra.
–
Using computer assisted stationaryphase development, the
phases have beenoptimized for these separations, resulting in
faster analysis times.
