ABSTRACT:
An ionization gas analyzer system includes an ionization chamber including ionization electrodes contained therein. The ionization chamber contains a test gas or gas mixture. A high voltage generator is coupled to the electrodes and provides variable high voltage pulses to the ionization electrodes. An ionization voltage analyzer is coupled to the ionization chamber and receives ionization voltage information from the plurality of ionization electrodes in response to the variable high voltages pulses. The ionization voltage analyzer produces a gas code identifier in response to the plurality of ionization voltages by defining a code based on which of the ionization voltages exceed an arbitrarily established reference level ionization voltage. A single ionization electrode system can be used to determine a concentration of a particular gas.
