Title: Gas chromatograph
Inventor: OTSUKI SATOSHI
IPC: G01N30/12
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of analysis by a constitution wherein a sample passed through a branch part is cold trapped again and overlap is eliminated by sharpening the peak of each component thereby enhancing the separation. SOLUTION: A sample S subjected to first cold trap 20 in a trap tube 3 is introduced again to the duct part 21a in a jacket from a T pipe through a duct 12 and liquid nitrogen LN is fed to the jacket 2 in order to trap and focus the sample S again. Subsequently, a current is fed instantaneously to the duct part 21a through voltage applying terminals 22a, 22b and the sample S is heated at a stretch. The focused sample S is evaporated under that state and introduced to a separation column 12. Since the sample S passed through a T pipe 9 is trapped and focused again, bandwidth of the sample S is reduced and the peak of each component is sharpened. Consequently, overlap of peak is eliminated and the separation is enhanced thus enhancing the accuracy of analysis.
