Abstract
A novel apparatus with a simple structure has been developed for introducing samples into the vaporizing chamber 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. Repetitive injection of samples with boiling points below 300 °C resulted in peak areas with relative standard deviations between 1.25 and 3.28% (n = 5) and good linearity (r2 > 0.9942) for the calibration curve. In the analysis of polycyclic aromatic hydrocarbons and a base oil, the peak areas of components with high boiling points increased as the injection port temperature was increased to 450 °C.
