Standard Practice for Determination of Volatiles in Polymers by Static Headspace Gas Chromatography

Importancia y uso:

4.1 There are various reasons why one would measure the level of unreacted or residual monomer, water, or other volatile components in a polymer sample.

4.2 Volatiles of interest are often at trace concentrations. Headspace analysis is suited for determination of these trace components which often cannot be determined by conventional gas chromatography because of sample decomposition or interferences.

4.3 For polymer analysis, sample treatment for headspace analysis is simpler than conventional gas chromatography, where additional precipitation steps are required to prevent polymer contamination of the chromatographic column.

4.4 This headspace practice will be able to determine qualitatively any component with sufficient vapor pressure. It is capable of yielding semiquantitative results and can be used for relative comparisons between samples.
