Patent ID: 8591630

Claim:
A method for fast gas chromatography analysis, said method comprising: injecting a sample to be analyzed into a gas chromatograph injector that is coupled to a gas chromatography capillary column; transferring said sample in said injector into said capillary column with a carrier gas flow; transferring said capillary column through a gas chromatograph oven as a flexible non-rigid capillary into a resistively heated metal tube having opposing input and output ends; locating the input and output ends of said resistively heated metal tube near a hole in the gas chromatograph oven body so that a substantial portion of said column in said heated metal tube is located outside said gas chromatograph oven and so that said input and output ends project a short distance inside said gas chromatograph oven; introducing an end of said portion of said capillary column that is outside the gas chromatograph oven from said heated metal tube into said gas chromatograph oven as a flexible capillary, wherein the capillary column and the resistively heated metal tube are configured such that transferring the capillary column through the gas chromatograph oven into the resistively heated metal tube and introducing the capillary column from the heated metal tube into the gas chromatograph oven is reversible, without removal of the resistively heated metal tube; connecting said flexible capillary with a transfer line that leads into a gas chromatograph detector; connecting both ends of said resistively heated metal tube to a power supply; and resistively heating said heated metal tube in a time programmed manner to facilitate fast temperature program of said capillary column; wherein said capillary column is flexibly connected to said gas chromatograph injector and detector.
