摘要

This plea for help is by a chromatographer with a modifier problem:I have several positively charged (amine) compounds, which, for chromatographic reasons, must be analysed using a basic (triethylamine) buffer mobile phase Because the mobile phase is only 0 1 % triethylamine and about 50% acetonitrile, I thought! could simply acidify the effluent with a postcoiumn infusion of formic acid (10:1 effiuent-formic acid) via a tee Unfortunately I cannot see anything, even at high sample concentrations Where am I going wrong?
