ASTM D7439

Determination of Elements in Airborne Particulate Matter by Inductively Coupled Plasma–Mass Spectrometry

Applicability: ASTM D7439 is used to provide a standardized method for measuring the concentration of metals and metalloids in airborne particulate matter, particularly in workplace air samples.

Purpose: ASTM D7439 uses inductively coupled plasma–mass spectrometry (ICP-MS) to determine the elemental composition of these samples, enabling accurate analysis for health and safety assessments.
