triethylamine analysis

[martinamarie]

Hi, can anyone tell me if triethylamine can be analysed by HPLC by forming a salt and detecting with UV detection, or would the analysis have to be with RI detection. Or is the only way to analyse triethylamine by GC
Thanks

Any of the above should work. Do a Google search for "triethylamine" + "indirect uv" and you'll come up with several links using capillary electrophoresis, but the same approach should work with HPLC.

A conductivity detector with a cation exchange column works also (I've done it that way in the early 80s)

Thanks Tom, I'm on it

Tina, amines have considerable absorption at or even above 200nm. Triethylamine has a max around 210nm.
