trying to find an equivalent column for HPLC-ELSD

[peoplehi5]

currently using Alltech Allsep Anion IC Column
100x4.6
2 micron frit
7 micron particle size
methacrylate based with quaternary ammonium functional groups
SS P/N: 51200

the current manufacturer has a problem having it in stock and being able to deliver it to us ...

I wasn't able to pull it up on the USP equivalent column page.

any suggestions?[/img]

I found one equivalent in hamilton, the PRP-X110(S) ...

I would still like to find at least one more ...

any suggestions would be great!!

Careful, the PRP-X110s column is not methacrylate based. Our PRP-X100, PRP-X110 and PRP-X110s are poly(styrene-co-divinylbenzene) based. We do have one methacrylate based anion exchange column, the PRP-X500 but it was designed for protein separations.
However, the PRP-X110s can be used for analysis of common anions in drinking water etc.
Let me know if you have any questions.

I was wondering what the difference was, I saw the USP L23 for the X500, but the others had showed up in another part of the search ...

the clarification was helpful ...

I will PM you with a few more questions
