A Completely Automatic Preparative Scale Gas Chromatograph
During recent years the use of gas chromatography for the separation and isolation of relatively large quantities of material has become increasingly popular. Although preparative scale chromatography is still used in conjunction with other techniques as an aid in positive qualitative identification of components, this application is becoming less important. Other applications, such as the preparation of spectroscopic solvents, pure materials for reaction studies, and perhaps even the isolation of valuable pharmaceuticals, require even higher sample capacities.
