Hi everybody¡

In my job, I usually do analyses of oil olive. One of this analyses is methil ester and when we contrast with reference sample, our results is more lower than the reference sample. We think that it is possible for the FID.

What do you think about this? and if the problem is the FID , which is the best form to clean it?

I expect your answer

THANK FOR ALL

There isn't enough information for us to think anything...

How do you prepare the sample for GC-FID? How do you quantify? What is your result and how far is it from the reference?

Do you have a reason to suspect the instrument (degrading peaks, bad separation,....)?
