Dear all,

I'm trying to find columns that complies with USP L 31 to perform an HPLC method...

I'm having trouble finding any brand with that kind of pakings

Any suggestions ?

Ask Phenomenex, their caltalogue say "please call'. It's probably a very good idea to email the USP and ask who supplies the column.

The columns with the USP designation L31 are Ion Pac AS 10, IonPac AS11-HC, IonPac AS16 from Dionex.

Thanks Uwe,

The problem is that Dionex does not sell its columns to a people that does not have a dionex HPLC .....

So I need a column different from Dionex ones..
