Methanol was designated under Title III of the Clean Air Act Amendments of 1990 as a pollutant to be regulated. The U.S. EPA, through a contract with Research Triangle Institute, has developed a test method for the measurement of methanol emissions from stationary sources. The methanol sampling train (MST) consists of a glass-lined heated probe, two knockout traps and three sorbent cartridges packed with Anasorb 747, a beaded, activated carbon. Anasorb 747 samples are desorbed with a 1:1 mixture of carbon disulfide and N,N-dimethylformamide. Samples are analyzed by gas chromatography with flame ionization detection. Following laboratory testing, field tests of the MST and the National Council for Air and Stream Improvement (NCASI) sampling method for methanol were conducted at a paper and pulp mill. The sampling location was an inlet vent to a softwood bleach plant scrubber. In accordance with EPA Method 301, two pairs of trains were run in parallel for six runs, collecting a total of twenty-four samples by each method.
