【原创】马来酸酐如何用ＧＣ进行分析

没有人知道吗？

Dillute in ethyl acetate or ethanol , nitrogen dryness, add 200uL BSTFA+TMCs(99:1) inject to gc inject volumn 1ul,
gc Temperature Program
Initial temperature: 80°C, increased at a rate of 10°C min-1 until 250°C
Injector / detector temperature: 250°C / 300°C
Carrier gas: Helium (Splitless in the first minute)
gc-FID

thank you very much!
another question is what kind of column will be used?

最好还是用液相色谱作，否则重组分对色谱系统有污染。如用GC，在稀释样品的时候最好加入硅烷化试剂
