[Current]Methods for sampling and analysis of ambient air, Method 9.8: Determination of suspended particulate matter - PM10 continuous direct mass method using a tapered element oscillating microbalance analyser
AS 3580.9.8: 2022 sets out a method for the continuous determination of suspended particulate matter in ambient air using a tapered element oscillating microbalance (TEOM). The method can provide a measure of mean particle concentration over periods from 10 min to 24 h
