ISO 17052:2007

ISO 17052:2007 specifies a method for the determination of residual monomers and other volatile low-molecular-mass compounds in raw rubber by capillary column gas chromatography using a thermal desorption (also known as dynamic headspace) method. It includes a generic section that is applicable to all types of raw rubber and two annexes specific to particular rubber types. This method has the advantages of not requiring a solvent, of concentrating the volatile compounds and of introducing them to the chromatograph in a very precise manner. The compounds found in the raw rubber which are to be determined are defined as residual monomers, solvents and other low-molecular-mass compounds in the boiling point range of C4 to C12 hydrocarbons. NOTE The limit of detection is 1 microgram per gram.
