Several issues can cause pentachloroethane to convert into tetrachloroethene during an analysis, and the resulting elevated level of tetrachloroethene and low-biased pentachloroethane response may lead to failed proficiency tests (PTs) when analyzing VOCs in solid waste by EPA Method 8260. This version of our popular MegaMix certified reference material (CRM) conveniently gives you 75 compounds in one ampul, but does not include pentachloroethane, so it is ideal for labs that either have had problems with the calibration of tetrachloroethene or do not need to report on pentachloroethane.
We also offer a single-component standard for pentachloroethane (cat.# 30404) for labs that experience elevated tetrachloroethene response but still need to test for pentachloroethane.
For an identical mix that does contain pentachloroethane, see our original mix (cat.# 30633).
Note: Vinyl acetate is a volatile organic ester included in the target lists of several US EPA and other methods. Under acidic conditions, esters react with alcohols to form new esters (transesterification). Methanol-based mixes containing halogenated compounds are slightly acidic, so it is important to minimize exposure of vinyl acetate to mixes of halogenated compounds in methanol. For this reason, we offer vinyl acetate in an individual solution (cat.# 30216) and suggest that it be introduced into the working level calibration solution immediately before use. This will minimize problems and ensure more consistent results.
