Abstract

We have constructed a low cost, portable, battery-powered quadrupole mass spectrometer for use in the analysis of gaseous, liquid or solid field samples. The system may be configured for continuous sampling of ambient gas samples, or for the analysis of small solid, liquid or gas samples in sealed glass vials. The system is capable of measuring partial pressures down to the 10-10 Torr range, and may be operated on battery power for several hours in a field deployment. In this paper, we present information on the design and testing of the instrument, as well as data taken on chlorinated hydrocarbons and other contaminants in water.
