Sulphuric acid aerosol in air may be determined after collection on a filter as equivalent to the amount [of] diaethylamine it absorbs from a stream of dry air to which this reactant has been added in vapour form. This amount may be determined by a simple photometric method. The detection limit is about 0-2 [microgrammes per cubic meter], the reproducibility is about 10 per cent. Other acidic particles interfere to an extent in the order of 20 per cent, depending on acid strength and physical state. 1, record 1, English, - acidic%20particle
