OTM-50 Mixture for PFAS Analysis
The OTM-50 mixture is one of the reference mixtures used in the Other Test Methods (OTM) developed by the US Environmental Protection Agency (EPA) for the measurement of volatile fluorinated compounds in industrial emissions, including PFAS.
It is a gas mixture containing 30 different short-chain perfluoroalkyl and polyfluoroalkyl substances that can be monitored as indicators of incomplete PFAS decomposition.
This gas mixture is available in light aluminium alloy cylinders of various capacities ranging from 1 to 50 litres.
The mixture is produced in accordance with preparation and analysis procedures developed in-house by SIAD’s Specialty Gases Laboratory.
