Introduction
In the environmental industry, the chlorinatedpesticides analytical methods often are the
most challenging to perform. Analysts strugglewith linearity, breakdown, and lengthy
calibrations; aswell as columnbleed, column reactivity and poor separation.
Advancements have beenmade to address these issueswith the development of new
columns that are designed specifically for the separation of chlorinated pesticides, to be
used in parallel for simultaneous quantification and confirmation by gas
chromatography/electron capture detection (GC/ECD). This paper will showapplications
using the newRtx-440 columnwith three different confirmation columns. The advantages
and disadvantageswill be discussedwith each column pair.
The three column pairs evaluated:
1.)
Rtx-440&Rtx-XLB
2.)
Rtx-440&Rtx-CLPesticides
3.)
Rtx-440&Rtx-PCB
