The feasibility and design requirements for the development of a portable mass spectrometer for industrial hygiene field use are reviewed. A set of design goals specifying analysis time, size, weight, operating time, transportability, mass range, resolution, limit of detection, control and data capability, and environmental requirements is summarized. Existing components and systems are evaluated in light of the requirements for portability and use under field conditions. Equipment under development, particularly the electro-optical ion detector, is evaluated. The relative rankings of mass analyzers, ionization sources, microprocessor families and displays are summarized. A gas chromatograph mass spectrometer system, a minimum separation system, and a state of the art system are described. The three systems are ranked according to performance, feasibility, time and cost of development, and final cost of production.
