I try to analyse ammonium and is doing fine chromatogram whith standard sample. But as soon I run a real sample the peek is flattern and real bad. It might bee due to to much phosporus acid? The ammonia is sampled on a filter impregnated whith phosphorus acid and my question is wheterornot the acid can disturb the equilibrium in the Ion-column? Thankful for all advise
