Sorry in advance if my IC vernacular is bad.
Our problem is this: our 1ppm standards for anions oxalate, formate, citrate and acetate have a tendency to show no peak if not made fresh. We are also running chloride, phosphate, sulphate and nitrate at the same time, but these standards have no issue at 1ppm. Our sister site that runs the same method does not see this problem. I thought maybe we have some cation contamination in our flasks or DI water causing some anion to precip out but not others.
Thoughts or ideas?
Thank you in advance!
