Development of septum-free injector for gas chromatography

Nov 03,2006· A novel apparatus with a simple structure has been developed for introducing samples into the vaporizing chAijiren of a gas chromatograph. It requires no septum due to the gas sealing structure over the carrier gas supply line. The septum-free injector made it possible to use injection port temperatures as high as 450 °C.
