Scope
Main technical content: This document specifies the solution absorption-hydrogen flame gas chromatography method for measuring methanol in ambient air. This document is applicable to the determination of methanol in ambient air and unorganized waste gas. When using 5 mL of absorption solution and a sampling volume of 20 L, the detection limit for measuring methanol in air is 0.05 mg/m3, and the lower limit of determination is 0.20 mg/m3.
