Abstract
A gas-chromatographic system working at inlet pressures to 2000 atm has been constructed. Data acquired on micro columns packed with 13-μ adsorptive particles are described. Results, although rather erratic at present, show efficiencies as high as 4000 plates/ft, or roughly 40,000 plates for a 3-m column. In addition, equilibrium migration rates show a strong dependence on pressure, with variations up to the fourfold level. The relationship of the present work to previous work; the experimental system; and the role of gas nonidealities are all discussed.Keywords
