EPA Method 8430:
ANALYSIS OF BIS(2-CHLOROETHYL) ETHER AND HYDROLYSIS PRODUCTS BY DIRECT AQUEOUS INJECTION GC/FT-IR

Summary:
Water samples are filtered through a 0.45 ?m filter, and 1 ?L aliquots are injected directly into a GC. The GC is equipped with 2 detectors, a thermal conductivity detector (TCD) and an FTIR. During analysis, the analyst disconnects the FT-IR from the system to prevent aqueous degradation of the KBr window, using an 8 port switching valve. Further analysis of either the solid precipitate from the filtering step or the aqueous filtrate for trace amounts of non-water soluble compounds may be done by extracting the samples using appropriate 3500 series methods.

Scope:
This method provides procedures for the identification and quantitation of bis(2- chloroethyl) ether and its hydrolysis compounds in aqueous matrices by direct aqueous injection (DAI) and gas chromatography with detection by a fourier transform infrared spectrometer (GC/FTIR).
