The result of the gas chromatography is not very accurate, so the rsd of the liquid chromatography is no more than 2%, and the gas chromatography is 10%. The main reason is that the injection error is very large.

If it is a headspace, you can adjust the balance time, headspace temperature or something.

For example, manual injection, the injection process itself has a certain error. This can only be practiced. Faster.
