title: Vacu-Samplers, a simple method for taking accurate quantitative gas and vapor samples using partially evacuated steel containers.
abstract: The Vacu-Sampler, a partially evacuated steel cylinder, has been widely used as a diagnostic industrial hygiene sampling system. This study examines the rational behind the Vacu-Sampler and two simple, quantitative procedures that can be used to obtain accurate sample results in ppm with gas chromatographic analysis.
