标准范围

ISO 17052:2007规定了使用热脱附（也称为动态顶空）法通过毛细管柱气相色谱法测定生胶中残留单体和其他挥发性低分子量化合物的方法。它包括一个适用于所有类型生橡胶的通用章节和两个特定于特定橡胶类型的附件。这种方法的优点是不需要溶剂，浓缩挥发性化合物，并以非常精确的方式将其引入色谱仪。待测定的生橡胶中发现的化合物定义为残余单体、溶剂和其他沸点范围为C4至C12碳氢化合物的低分子量化合物。注:检测限为每克1微克。

ISO 17052:2007 specifies a method for the determination of residual monomers and other volatile low-molecular-mass compounds in raw rubber by capillary column gas chromatography using a thermal desorption (also known as dynamic headspace) method. It includes a generic section that is applicable to all types of raw rubber and two annexes specific to particular rubber types.This method has the advantages of not requiring a solvent, of concentrating the volatile compounds and of introducing them to the chromatograph in a very precise manner.The compounds found in the raw rubber which are to be determined are defined as residual monomers, solvents and other low-molecular-mass compounds in the boiling point range of C4 to C12 hydrocarbons.NOTE The limit of detection is 1 microgram per gram.
