The Stability of Sulfur Compounds, Low Molecular Weight Gases, and VOCs in Four Air Sample Bag Materials

Sampling bags have been used for many years to collect grab samples of gas and vapor contaminants in the air. Originally developed for the industrial hygiene market, sampling bags have also gained popularity in environmental applications including the following:

(1) investigating odor complaints at factories, refineries, and waste water treatment plants

(2) sampling high vapor pressure materials where solid sorbents are unsuitable,

(3) sampling in landfills

(4) transporting and preparing calibration standards for direct-reading instruments and gas chromatography.
