Hi Natthanicha,

It depends on the volume of available samples and on the level of detail that you need and the characterisation systems you can dispose of.

You might think to use either a standard ASTM D86 distillation (if you dispose of an acceptable volume of product) or evaluate the use of NIR Spectroscopy.

Hope it helps.

Thank you for your kind information.

I have reviewed some pieces of literature and found that they use GC-FID to identify liquid products in this kind of research work.

In my lab, we have only GC-FID and GC-TCD

However, I do need to know more about how they make a standard GC for sample. The point is it has too many kind of products which may be difficult to make it all the component. I only need to know the quantitative or selective to calculate the products according to carbon numbers.

I hope you could share with me more of your knowledge and experiences.

Thank you,

Natthanicha.

I think you can refer to ASTM D3710 "Standard Test Method for Boiling Range Distribution of Gasoline and Gasoline Fractions by Gas Chromatography" https://civilengineersstandard.com/wp-content/uploads/2019/02/D-3710.pdf

This document should give you hints to replicate the method in your lab.
