Abstract
An inexpensive sampler has been developed whereby air samples can be collected in plastic bags without pump contamination and shipped to a laboratory for analysis. Data are presented to illustrate how well these bags contain (1) sulfur dioxide, nitrogen dioxide, and ozone in samples collected from synthetically prepared mixtures, and (2) hydrocarbons in samples collected from an auto exhaust irradiation chamber. The inorganic samples were in the concentration range of 0.5 to 1.5 ppm, and the hydrocarbon samples were in the concentration range of 7 to 20 ppm, The samples were stored for periods of several days.
