GAS CHROMATOGRAPHIC METHOD FOR SELECTIVE ISOLATION OF TARGET COMPOUND FROM COMPLEX SAMPLES IN THE GAS PHASE

摘要

PURPOSE: A method for selectively separating target materials from a gaseous mixture is provided to improve separation power and to reduce or eliminate the treating processes of specimens. CONSTITUTION: Single materials are separated from a mixture based on the capillary column of gas chromatograph. Target materials are selectively re-separated from the single materials by using a switch. The target materials are separated by using a cooling unit. The target materials are verified using a detector. The switch and the cooling unit are connected by a connecting pipe. The detector is in connection with the switch of the re-separating process by the connecting pipe.
