GC Analysis of US EPA Method 504.1
Organochlorine Pesticides, Using
the Rtx®-CLPesticides and
Rtx®-CLPesticides2 Columns
A versatile column pair for analyzing
organochlorine pesticides, herbicides, or PCBs
Analysts following Method 504.1 in
monitoring 1,2-dibromoethane (EDB),
1,2-dibromo-3-chloropropane (DBCP), and
1,2,3-trichloropropane (TCP) in drinking
water will value Rtx®-CLPesticides and
Rtx®-CLPesticides2 columns because this
same primary column/confirmation column
pair can be used to perform numerous
related analyses: organochlorine pesticides
(e.g., by EPA Method 608 or 8081),
herbicides, or polychlorinated biphenyls
(PCBs). Details in this 2-page note show EDB,
DBCP, and TCP are fully resolved from
common interference compounds, per
requirements of Method 504.1.
Applications Note
lit. cat.# 59539
Rtx®-CLPesticides and Rtx®-CLPesticides2
columns also are ideal for:
•Triazine herbicides
(lit. cat.# 59101)
•PCBs
(lit. cat.# 59120)
•Chlorinated pesticides
(lit. cat.# EVAN1197)
•Chlorinated pesticides, PCBs, & chlorinated
herbicides
(lit. cat.# EVFL1013)
