Pyrolysis gas-liquid chromatography, used in the qualitative analysis of saccharin, has provided reproducible pyrograms which permit direct characterization of these sweetners in a variety of commerical saccharin tablets and diet beverages. This method was used also to identify the salt, after conversion to the free imide, in a commercial multivitamin product. The tablet analysis required isolation by solvent extraction. Analyses were carried out on quantities ranging from 1 to 100 mug. The sensitivity of the method could be increased by addition of a pure sample of the compound sought to the unknown.
热解气相色谱法用于糖精的定性分析，已得到可重现的热解色谱图，该图能直接对多种市售糖精片和减肥饮料中的这些甜味剂进行表征。该方法还用于在将一种商业多种维生素产品中的盐转化为游离酰亚胺后对其进行鉴定。片剂分析需要通过溶剂萃取进行分离。分析的量范围为1至100微克。通过向未知物中添加待检测化合物的纯样品可提高该方法的灵敏度。
