I'm a newby to Wikipedia, just wanted to make a minor edit to an article. I'm retired and have a Ph.D. in Chemistry. I'm familiar with most types of instrumented chromatography including HPLC, UPLC to some extent, various methods of detection including UV-Vis, Refractive Index, Mass Spectrometry, Fluorescence, Conductivity, and Electrochemistry.
