The application of EPA test method (M-6) to the analysis of higher sulfur dioxide concentrations than had previously been employed has been studied. The use of prepared gas mixtures showed that the method is efficient for the measurement of gaseous sulfur dioxide in concentrations of up to 80,000 mg/m. The investigation also showed no evidence of retention of significant quantities of sulfur dioxide in the isopropyl alcohol bubbler or of the production of sulfur compounds that are insensitive to barium-thorin analysis. When multiple impinger trains were employed, analysis of individual impinger contents showed that more than 99% of the sampled sulfur dioxide was collected in the first two impingers, even at the higher concentration, except when sufficient sample was collected to deplete the hydrogen peroxide in the absorbing solutions or when excessively high flow rates were used. These results contradict earlier reports that Method 6 suffers from a negative bias at high sulfur dioxide concentrations.
