专利汇可以提供Chromatograph专利检索,专利查询,专利分析的服务。并且PURPOSE: To expand the application range of a supercritical fluid chromatograph method by using the inorg. liquefied gas (in the subcritical state) which is maintained at the critical temp. or below even if the gas is compressed to the state of liquid as a chromatograph medium.
CONSTITUTION: The inorg. liquefied gas which is maintained at the critical temp. or below (subcritical state) even if the gas is compressed to the state of liquid, for example, gaseous CO
2 , N
2 O, NH
3 or the like is used as a chromatograph medium to be used in the separating means of a material. Such gas is maintained at about the critical temp. even if the gas is compressed to liquid density and the viscosity of the moving phase is fixed at the specified density of the moving phase. As a result, the application range of a supercritical fluid choromatograph method is expanded to the range where a thermally unstable compd. and the compd. diluted by a low boiling solvent are handled without spoiling the efficiency of the chromatograph.
