Trimethylamine in water

[yaakov]

I need to analyze TMA in water. I tried DBWAX but a significant tailing was obtained.
How can I improve a form of peak?

[Don_Hilton]

Amines are not easy to analyze by GC. There are some columns that have been optimized for amines, and it would be worth trying one of them.

I also have Stabilwax, CP..Amine. What do you think about them?

[chromatographer1]

Water may damage any column you chose to use.

Do you have the ability to use ion chromatography?

Porapak or Hayesep P, or Chromosorb 101 might be a better solution to your problem.

You could also use Chromosorb 103.

Good luck,
