WebI’ve written several times on the operational principles and variables used in UV detection, but I also get asked questions on the basic theory of UV detection and this time I’m going to address some of those FAQ’s to give a little more background theory as well as some operational tips and tricks. Q1. WebThe HPLC column is housed in an oven (like in GC), so the temperature of the column can be altered as needed to give a better separation. The detector will sense the identity of the separate compounds by UV-visible spectroscopy or MS (mass spectroscopy), depending on the type of HPLC purchased. Separated compounds are collected as fractions. 2
