Scope

This document specifies a method for determining residual monomers and other volatile low-molecular-weight compounds in raw rubber using thermal desorption (dynamic headspace) capillary column gas chromatography analysis technology, including a general section applicable to all types of raw rubber and two appendices for specific types of rubber.
The advantage of this method is that it does not require solvents and can accurately introduce volatile compounds into the gas chromatograph after concentration.
This document is suitable for determining residual monomers, solvents, and other low-molecular-weight compounds with a boiling point range of C4 to C12 hydrocarbons in raw rubber.
Note: The detection limit of this method is 1 μg/g.
