AS 3580.3.1 – Methods for sampling and analysis of ambient air – Part 3.1: Determination of acid gases – Titrimetric method

Sets out a titrimetric method for the determination of acid gases (expressed as sulfur dioxide) in ambient air. The method is applicable to ambient air in which the sulfur dioxide concentration ranges from approximately 0.007 ppm to 3.5 ppm by volume (20 µg/m(sup)3(/sup) to 10 000 µg/m(sup)3(/sup)).
