聚合物降解的两种技术已独立地并入常规气相色谱装置中，从而布置成使得载气将降解产物直接扫入分析柱中。涉及在长丝上热解的方法已被证明是最通用的，因为可以选择高达1000°C的任何温度进行降解。给定聚合物在多个温度下的色谱系列给出了聚合物的快速和明确的表征。对共聚物和聚合物混合物色谱图的定量测量使其组成的测定精度优于2%。
Two techniques of polymer degradation have independently been incorporated into a conventional gas chromatography apparatus, so arranged that the carrier gas sweeps the degradation products directly into the analysis column. The method involving pyrolysis on a filament has proved most versatile, since any temperature up to 1000°C may be selected for the degradation. The chromatogram series for a given polymer at a number of temperatures gives a rapid and unambiguous characterization of the polymer. Quantitative measurements on the chromatograms of copolymers and polymer mixtures enable their composition to be determined with an accuracy better than 2 per cent.
