Workplace atmospheres. Determination of inorganic acids by ion chromatography - Part 1: Non-volatile acids (sulfuric acid and phosphoric acid)1 Scope This part of ISO 21438 specifies a method for the determination of the time weighted average mass concentration of sulfuric acid and phosphoric acid in workplace air by ion chromatography. The method is applicable to the personal sampling of the inhalable fraction of airborne particles, as defined in ISO 7708 and to static (area) sampling. The analytical method is applicable to the determination of masses of 0,005 mg to 2,0 mg of sulfuric acid
