Lab 5Gas Chromatography/Mass Spectrometry (GC/MS

Aug 15, 2020· Gas chromatography is a physical method of separation in which the components to be separated are distributed between two phases, one being a stationary bed of large surface area, and the other a gas that percolates through the stationary bed. When the stationary phase is a solid, the separation process is more precisely called gas-solid
