1 Scope
This document specifies a thermal desorption (dynamic headspace)-capillary column gas chromatography analysis technique for the determination of residual monomers and
Methods for other volatile low-molecular-weight compounds, including general sections applicable to all types of raw rubber and types-specific sections
Two appendices.
The advantage of this method is that no solvent is needed, and the volatile compounds can be concentrated and accurately introduced into the gas chromatograph.
This document is applicable to the determination of residual monomers, solvents and other low components with a boiling point range between C4~C12 hydrocarbons in raw rubber
quantum compound.
Note. The detection limit of this method is 1 μg/g.
