I'm having trouble with reproducibility in my chromatograms. I noticed that the needle of my autosampler was dripping liquid every time it moved. Should I assume that the needle is damaged and needs to be replaced, or could there be other settings that would help with this problem?
I'm also struggling with some very big air bubbles caught in the syringe. How do I get rid of them? Reply to ABenson RE: Dionex - ICS-3000
