发明名称 DISCHARGE IONIZATION CURRENT DETECTOR AND ANALYZER PROVIDED WITH THE SAME
摘要 PROBLEM TO BE SOLVED: To provide a discharge ionization current detector capable of accurately calculating a flow rate or linear velocity of a sample gas in a column, and to provide an analyzer provided with the same.SOLUTION: A discharge ionization current detector includes a pressure sensor 7 for measuring pressure in a detector body 1. Since the pressure in the detector body 1 can be accurately measured by the pressure sensor 7, a flow rate or linear velocity of a sample gas in a column 2 can be accurately calculated by using the measured pressure value in the detector body 1. Further, by adjusting a flow rate of a plasma generation gas supplied from a plasma generation gas supply path 3, on the basis of the pressure in the detector body 1 measured by the pressure sensor 7, a concentration of a sample component in the detector body 1 can be always kept at a constant level, even when the flow rate of the sample gas in the column 2 fluctuates. Thereby, since analysis can be conducted with constant sensitivity, the analysis of the sample gas can be performed excellently.
