ABSTRACT:
A corona discharge device capable of use as an ionization detector or as a solute switch. Corona discharge pulses of short duration, preferably not exceeding one microsecond, can ionize a gas flow through the device. In the detector mode, electrons produced by the corona discharge can react with a compound to be detected in the gas flow. In the switching mode, the device converts a compound in the gas flow into a reaction product, and fluctuations in output signal of a detector connected to receive flow from the device correspond to the switching frequency of the device and are indicative of the compound in the gas flow.
