Personal Atmosphere Sampler.
Abstract
This patent application discusses an apparatus which is used for taking a time integrated sample of an atmosphere. It is comprised of a canister evacuated to a vacuum of at least one half of the pressure of the atmosphere to be sampled and a critical orifice in the inlet. The air sampler can be easily carried by an individual and it does not require a motor in order to operate. It is a sampler which can sample low as well as high molecular weight compounds, and finally it can give a time integrated sample for periods up to 8 hours and timeweighted averages for individual exposures.
