Abstract
From the fact that the electron current following a glow discharge of N2 was markedly influenced by mixing a small amount of other gases, a new detector for a gas chromatograph was designed. The glow discharge was generated by applying 2-3×103 V of 1 Mcps from outside the glass discharge tube.
The electron current was measured through three single collector electrodes sealed at different positions, 5, 10 and 15cm distant from the discharge electrodes. The detector was sensitive to both O2 and CO2, and their peaks appeared on opposite sides of the N2 level.
Since N2 gas may be used as the carrier gas, and the structure of th equipment is very simple, this detector may be very useful in analysis of respiratory gases.
