Patent JP-H0251061-A (JP)
Title: Gas chromatograph
Inventor: NAGAI HISAAKI
IPC: B01D15/08
Filed: 1988-08-12
Abstract: PURPOSE:To realize a highly sensitive detection of a trace component by arranging a branch passage having a column to keep a flow rate of a carrier gas constant free from a switching of a selector valve with the adjustment of a passage resistance. CONSTITUTION:A carrier gas is adjusted with a flow rate adjustor 1 to be branched off with a sample introducing section 2. A part of the carrier gas reaches a detector 8 from a selector valve 3 and a column 5 while the other part thereof does the detector 8 via the selector valve 3 and a column 6. Here, when a sample is introduced to an introducing section 2, it is separated with the column 5 to be detected with a detector section 8. Then, when the valve 3 is switched, the sample enters the column 6 via a passage resistance 9 from the valve 3 and components left unseparated by the column 5 are separated to be detected with the detector 8. At this point, if the carrier gas is allowed to flow at the same flow rate to the columns 5 and 6 by adjusting the flow rate resistance 9, the background of the detector 8 remains unchanged free from a switching of the valve 3, thereby enabling highly sensitive detection of a trace component.
