Hi all!
We are running HPLC in cesium formate solution to separate and detect sulfate. The solution might contain oxalate and some 2-acryl-amido 2 methyl propane sulphonic acid. Can one of those cause interference of the sulfate determination? Prior to diluting the sample 100 times, the weight % CsFormate (CsHCOO) is +/- 75%.
Thanks for any help to this!

Probably not but what is your column, detector and eluent system?
