Scope

Main technical content: This document specifies three testing methods for determining the methylcyclosiloxane content in silicone wastewater using liquid-liquid extraction-gas chromatography/mass spectrometry, headspace-gas chromatography/mass spectrometry, and purge-trap-gas chromatography. The liquid-liquid extraction-gas chromatography/mass spectrometry method is suitable for determining the methylcyclosiloxane content in water samples with a concentration of 0.1 μg/L to 250 μg/L. The headspace-gas chromatography/mass spectrometry method is suitable for determining the methylcyclosiloxane content in water samples with a concentration of 0.01 μg/L to 100 μg/L. The purge-trap-gas chromatography method is suitable for determining the methylcyclosiloxane content in water samples with a concentration of 0.3 μg/L to 1000 μg/L. This document is applicable to the determination of methylcyclosiloxane content in silicone wastewater and surface water that do not contain solids or gels.
