    Significance and Use

    5.1 Sulfuric acid is used in the manufacture of fertilizer, explosives, dyestuffs, other acids, parchment paper, glue, lead acid batteries, textiles, etc., and in the pickling of metals.

    5.2 This test method has been found to be satisfactory in the measurement of sulfuric acid for comparison with relevant occupational exposure limits.

    1. Scope

    1.1 This ion chromatographic test method describes the determination of sulfuric acid mist in air samples collected from workplace atmospheres on a mixed cellulose ester (MCE) filter.

    Note 1: Other filter types such as quartz fiber, polytetrafluoroethylene (PTFE), and polyvinyl chloride (PVC) filters are also suitable.

    1.2 The lower detection limit of this test method is 0.001 mg/sample or 0.017 mg/m3 of sulfuric acid (H2SO4) mist in 60 L of air sampled at 1 L/min.

    1.3 This test method is subject to interference from soluble and partially soluble sulfate salts. Other sulfur-containing compounds can be oxidized to sulfate and also interfere.

    1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.5 No detailed instrument operating instructions are provided because of differences among various makes and models of ion chromatography (IC) systems. Instead, the analyst shall follow the instructions provided by the manufacturer of the particular instrument, analytical column, and suppressors used.

    1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 9.
