PCB Analytical Method Solutions
The practice of analyzing for marker PCBs (congeners that are most prevalent in technical mixtures) and WHO PCBs (congeners that exhibit “dioxin-like” toxicological activity) has become routine practice in analytical laboratories. Congener specific analyses are also very important since commercial PCBs can vary in composition on a lot to lot basis and can change once they age in the environment.
Wellington offers method sets, which include calibration kits and support solutions, for the GCMS analysis of PCBs by the following methods:
- U.S. EPA Method 1668C
- U.S. EPA Method 1668
- Environment Canada Method 1/RM/31
- BS-EN 1948-4:2010 (previous draft method = prCEN/TS 1948-4)
The electrophilic chlorination of biphenyl leads to complex mixtures of chlorobiphenyl (PCB) congeners ranging from monochloro- up to decachloro-biphenyl. Although 209 PCB congeners are theoretically possible, only about 150 are found in industrial mixtures and have ended up in the environment.
Certain PCB congeners are considered more toxic than others and are termed ‘dioxin-like’. For this reason there are analytical methods that target only these ‘dioxin-like’ PCBs, while other methods focus on the major PCB congeners in the industrial mixtures. In addition, there are methods that address both groups of PCB congeners.
Wellington has designed, prepared, and offers a number of sets of calibration kits and support solutions for the analysis of individual PCB congeners.
WP-CVS
This set of solutions is to be used for the analysis of the 12 dioxin-like PCB congeners by HRGC/HRMS.
EPA Method 1668C
This series of calibration solutions, and corresponding support solutions, were prepared to be used according to U.S. EPA Method 1668, Revision C.
EPA Method 1668
This calibration kit and support solutions were designed and prepared to be used with the Draft version (March, 1997) of U.S. EPA Method 1668 which is still popular with some laboratories.
EC-9605-CVS
Environment Canada Method 1/RM/31 is a HRGC/LRMS method for PCB analysis and these solutions were prepared to be used with this method.
P48-W-CVS and P48-M-CVS
European Standard Method EN 1948-4 is to be used for analysis of the 12 ‘dioxin-like’ PCB congeners and the 6 ‘marker’ PCB congeners in stationary source emissions. These two calibration kits, and their support solutions, were prepared for this method.
WM48-CVS
This calibration set is a combination of P48-W-CVS and P48-M-CVS.
We also offer solutions to test the resolution of common HRGC columns for 2,3,7,8-TCDD and 2,3,7,8-TCDF and set retention time windows for PCDD and PCDF congener groups.
