Can I use ethyl ether as solvent for GC-FID analysis?

[rodrigaoman]

I need to use a solvent with very low boiling point in GC-FID (because I have an impurity co-eluting with methanol/chloroform/ethyl-acetate).

I never heard about using ethyl ether as GC-FID solvent. Can I use it?

Thanks,
Rodrigo Borges

I'd guess it's going to be pretty hard to get that injected in the GC with any repeatability. You've looked at alternative stationary phases?

[rodrigaoman]

It's ok if I have poor repeatability.
Can I use it as GC-FID solvent?

Yes

Can you instead use a solvent that elutes AFTER the analytes of interest?

[Jumpshooter]

BOrges: you can also modify your oven temperature ramping program so that the solvent front elutes before the analytes of interest. For ex: if your solven is "hexane" then start the oven at 40C with 10 psig Press and hold for 30 secs. Your analytes ought to elute after this huge solvent peak. Thanks for your question.

rodrigaoman,

I would advise split injection, even if only 2:1 or 5:1 in order to make the solvent front as narrow as possible. I hope you are in a cool locale and at sea level... It would not work where I live.

Best regards,

I used it!
As I didn't mean to quantify anything, just identify, it worked very gook.
Very flat baseline!!!
Impurities just appeared around the solvent.
Unfortunatly it didn't came up as fast as I wanted, but that's ok.

Thank you all!
