I have been using one of the traditional phases for my pesticide analysis.What are
someof the troublesomepesticideseparationson thesephasesandhowdoes theRtx®-
CLPesticides column pair overcome these?
Rtx®-CLPesticides andRtx ®-CLPesticides2 columns: Both columns provide baseline
separation of the 22 chlorinated pesticides listed inEPAMethod 8081within 24min-
utes.Maximum operating temperature is 330°C.
5% phenyl phase: Difficult separation of b -BHC/ g -BHC, endosulfan I/a -chlordane,
and 4,4'-DDE/dieldrin.Analysis time is 32minutes.Maximum operating temperature
is 330°C.
35%phenyl phase: Difficult separationof g -BHC/aldrinand a -chlordane/endosulfan I.
Analysis time is 26minutes.Maximum operating temperature is 310°C.
1701cyanopropylphase: Baseline resolutionof22pesticides inUSEPAMethod8081.
Analysis time is 28minutes. Maximum operating temperature is 280°C. May see on-
columnbreakdownofDDT andmethoxychlor as a result of degradationof the station-
ary phase.
50% phenyl phase: Difficult separation of a -chlordane/endosulfan I.Analysis time is
25minutes.Maximum operating temperature is 310°C.
