  • Ionization flow detector
    Patent number: 3996795
    Abstract: An electrode E.sub.1 having the design function of an ion source is placed in a gas stream and emits by corona discharge effect ions which are collected on two electrodes E.sub.2 and E.sub.3. These electrodes consist of grids placed at right angles to the direction of the gas stream on each side of the electrode E.sub.1 at approximately equal distances from this latter. The device comprises electronic means for amplifying the currents collected at the electrodes E.sub.2 and E.sub.3 as well as for calculating the difference and the sum of the currents collected at the electrodes after amplification.
