Importers construction adhesive
Determination of phosphate-based plasticizers
1 Scope
This standard specifies the import and export of six buildings with an adhesive phosphate plasticizers (trimethyl phosphate, triethyl phosphate, tri-butyl phosphate
, Tris - (2-chloroethyl) phosphate, tris - measuring method (2-ethylhexyl) phosphate, triphenyl phosphate) content, including a first gas phase method
Chromatography - mass spectrometry (GC-MS) method and the second gas chromatography (GC). Gas chromatography - mass spectrometry for the arbitration law.
This standard applies to the import and export construction adhesive trimethyl phosphate, triethyl phosphate, tributyl phosphate, tris - (2-chloroethyl)
Phosphate, tris - (2-ethylhexyl) phosphate, triphenyl phosphate content was measured.
2 The first gas chromatography - mass spectrometry (GC-MS method)
2.1 Principle
Sample was extracted with methanol, the extract was filtered by gas chromatography - mass spectrometry and validation, external standard.
2.2 Reagents and materials
2.2.1 Methanol. chromatographically pure.
2.2.2 phosphate plasticizers standards. Table 1.
