EPA Contract Lab Program (CLP) Statement of Work (SOW) OLC03.2 is an analytical method for the detection of low-concentration volatile, semivolatile, and pesticide/Aroclor organics in aqueous samples using deuterated monitoring compounds (DMCs) as sample-by-sample accuracy indicators. Restek supports this method with a convenient VOA MegaMix (with m- and p-xylene isomers at half the concentration of other components), a deuterated monitoring compounds (DMCs) mix (cat.# 31810), and single-compound solutions of 3,3'-dichlorobenzidine (cat.#s 31026 and 31835), and 4-chloroaniline (cat.# 31211).
