Is there any method to estimate the related impurities by Gas chromatography FID for triethanol amine?

we dissolve in pyridine, derivatize with BSTFA (steam bath 15 minutres), assay on methyl silicone capillary.

We have used the Restek RTx-5 Amine column for direct analysis of amines. Ethanol amines might be another story though.
