This document specifies a method for the determination of certain cyclic volatile methylsiloxanes (cVMS) in environmental water samples with low density polyethylene (LDPE) as a preservative and subsequent liquid-liquid extraction with hexane containing the internal standard substances 13C-labeled cVMS1). The extract is then analysed by gas chromatography-mass spectrometry (GC-MS).
This document is applicable to the measurement of the following cVMS in rivers, streams, and waste water (influent and effluent):
Analytes determined by this method
Octamethylcyclotetrasiloxane, Decamethylcyclopentasiloxane, Dodecamethylcyclohexasiloxane,
This method can be used to determine cVMS from 0,1 μg/l to 250 μg/l. In very controlled laboratory environments, extremely minimizing contamination, the lower end of the application range can be diminished by a factor of up to 10.
