Can ethanolamine in sample influece determination Acetates and Formates?
I use Metrohm 930 IC flex with chemical suppresion and sample preconcentration.
I figured, when I mesure sample in Dionex IC 2500 (without preconcetrator, I use 2ml sample loop) and when I same sample mesure in Metrohm 930 IC flex so between results are big deviation.
Deviation is only between Acetates and Formates, other anions are without deviation. I provide determination in ppb range.
Thank
