Workplace air quality. Determination of isocyanate in air using a double-filter sampling device and analysis by high pressure liquid chromatography Ingestion-build-264231 This International Standard specifies a1 Scope This International Standard gives general guidelines for the sampling and analysis of airborne isocyanates in workplace air. This International Standard is appropriate for organic compounds containing free isocyanate functional groups and is specific for the quantification of monomers, polymers and prepolymers, vapours and aerosols. Differential air sampling is performed with a segregating device which can show the physical state of the
