ABSTRACT:
A differential microdischarge detector system. The system comprises two microdischarge detectors (MDDs). One of the MDDs is connected to receive sample analytes to be measured, while the other MDD is connected to receive a reference sample that contains interfering gases and none or a much lower concentration of the sample analytes to be measured. The outputs of the two MDD's are fed to a circuit that generates either a difference or a ratio between the measurements of the two MDDs. In addition, the current, impedance or voltage across the electrodes of the two MDDs may be measured and processed to generate either a difference or a ratio signal, thus obtaining additional information about the sample gas analytes.
