NIOSH 1976 Jul:75-105
Sulfur dioxide sampling and analysis using solid sorbents are discussed, presenting a schematic diagram of gas-handling apparatus for performing adsorption-desorption studies of pollutants at ppm concentration levels, and data on adsorption test apparatus and mass spectrometer. Data are also given on mass spectrometric and instrumental parameters. A list of sorbents that have affinity for sulfur dioxide is given. The right kind of sorbent should be capable of retaining the sorbed sulfur dioxide for periods up to two weeks without loss or conversion of the gas. Data obtained from various storage experiments indicate that the lowest limit of detectability for sulfur dioxide can be determined by using the Molecular Sieve 5A sorbent.
