6 October 1994 Recent developments for trace vapor detection
Author Affiliations +
A transmission quadrupole mass spectrometer has been incorporated in an integrated trace vapor detection system. The system includes high performance sample acquisition and inlet provisions to maximize detectability at very low levels. To characterize performance credibly, a precision sample generator with a down stream switching capability at levels below part per billion has been constructed. Construction and operation is reported.
