Conclusion
The newRtx
®
-440 column is an excellent addition
to the selection of innovative columns available
fromRestek.The column exhibits high thermal
stability and, for organochlorine pesticides, a
selectivity alternative to theRtx
®
-CLPesticides2
column. AnRtx
®
-440 column can be pairedwith
anRtx
®
-CLPesticides2 column to ensure sub-10-
minute analysis times for organochlorine pesti-
cides, or can be used as a confirmation column,
with anRtx
®
-5Sil MS or anRtx
®
-CLPesticides2
column, for GC/FID analysis of PAHs.
