NIOSH 1991 Feb:289-297
A portable gas chromatography/mass spectrometry system was developed for use in situations where site location, contamination, or terrain restrict access. Efforts to obtain maximum power and weight reduction using the Hewlett Packard MSD as a starting point were being undertaken. A gas chromatography/mass spectrometry system based on the combination of an automated vapor sample inlet, a transfer line gas chromatography module, and a modified Hewlett Packard model 5971A quadrupole MS system were used. The system used a 150 to 200 watt battery power pack and weighed about 70 to 75 pounds. The operator would wear a harness to support the mass spectrometer and computer in front of him. The carrier gas supply and roughing vacuum system were in a backpack. The system can operate continuously for 6 to 10 hours and with some modification was expected to weigh less than 50 pounds. Without vapor preconcentration, practical detection limits appeared to be in the low parts per million range. In order to facilitate detection of relatively nonvolatile species and to increase the range of compounds that can be analyzed in a single run, the development of rapid temperature programming capabilities was being considered. The completed system should be available for a broad spectrum of field applications ranging from hazardous waste sites and industrial or natural disaster areas to reconnaissance drones, space stations, interplanetary probes, and autonomous vehicular robots.
