A Study on the Types of Coulombs in GC and HPLC

Abstract

This study is looking for two types of advanced and accurate analytical devices in analytical chemistry, both of which depend on the phases that the material passes through and on its concentration; They are sensitive to the lowest concentrations up to 0.001 ppm. as well as the search for the most important component parts of each device and for the materials that have a measure in these devices (gas chromatography and highperformance liquid chromatography) where the two are similar in terms of the presence of columns and detector. The most important applications for each device and the most important areas it serves were also identified.
