摘要
采用裂解气相色谱 /质谱法对涂料组成成分进行测定 ,适用于各类涂料样品 ,避免了红外、核磁等需经化学分离、提纯方可进行定性测定的繁复冗长的分离步骤 ,具有样品无需前处理、用量少、灵敏度高、谱图直观、分析周期短等特点 ,不仅可确定涂料基料和溶剂的大类 ,还可对每类树脂的具体品种。
The coatings composition is analyzed by use of pyrolytic chromatography / mass spectrometry, which fits various coatings samples, avoiding the complex chemical separation, purification processes with IR and NMR methods. It is featured by free pretreatment, small quantity of samples, higher sensitivity and short test time, which can not only determine the binders and solvents, but also suitable for ingredient analysis of specific resin.
