Recovery of amino columns...how?????

[Jeane]

Hello, anyone here has a clue about how to recovery an amino column that is dying with only 2 month of mid use?

The column is a carbohydrate column and it's supposed to be basic...

I had washed with ACN/ TEA but nothing happened. I saw in some catalogue that Triethanolamine was suitable too. Anything more or should I just put it in the garbage?

Depends on what the problem is? Please specify the problem!

Hi,
What's the detector (ELSD, UV)? if you use an UV detector what about wavelenght?
did you try to inject column mix test in the same conditions of the manifacturer?
Good luck
