Study to determine the effect of mositure on volatile organic compuound recovery rates for thru-the probe audits into stainless steel canisters

摘要

Thru-probe (TTP) audits of criterial pollutants have been a part of the California Air Resources Board's (ARB) quality assurance program since 1982. The TTP audit allows us to check the integrity of the entire sampling and anlysis phases of ambient air pollution monitoring. By auditing thru-the-probe we can detect not only problems associated with instrument calibration and operation, but also problems associated with the station probe line from leaks or contamination.
