Organic acid column

hello,

I need to purchase a new organic acid column. I've used such from both Grace/Alltech (Prevail OAC) and Restek (Allure OAC). Neither's Tech Help was very helpful how to rinse the column to prolong column life post-analysis, said these OA columns were different than typical columns, but the column came with instructions for typical columns.

My peak shapes are getting worse over time, like for citric acid. I'm also doing other organic acids in the same injection but am not able to disclose those identities right now.


Please help.
Thanks!

I didn't find the right solution from the Internet.
