This document specifies the sampling and analysis of phthalates in indoor air and describes the sampling and analysis of phthalates in house dust and in solvent wipe samples of surfaces by means of gas chromatography-mass spectrometry (GC-MS). Two alternative sampling, sample preparation and sample introduction methods, whose comparability has been proven in an interlaboratory test, are specified for indoor air. Sampling may be performed using sorbent tubes sampling which are subsequently prepared by thermal desorption and analyzed by GC-MS. Alternatively, sampling may be performed by adsorption onto other sorbents, as described in Annex B, which are subsequently analyzed by solvent extraction and GC-MS. Committee NA 134-04-04-03 UA "Bestimmung organischer Stoffe in Luft" ("Assessment of organic substances in air") at DIN is responsible for this document.
This document replaces DIN ISO 16000-33:2017-12 .
