Photoionization detector automated zero level calibration

A method of detecting gas includes determining and storing, by a controller, a zero level of a photoionization detector using ambient air inflow when an ultraviolet lamp is in a turned OFF state, wherein the stored zero level is based on an ambient temperature; sampling, by the controller, an output of a detector electrode of the photoionization detector when the ultraviolet lamp is in a turned ON state; and comparing the sampled output of the detector electrode to the stored zero level to determine if a threshold concentration of a gas is present.

Optogalvanic effect detection system

An optogalvanic effect (OGE) detection system utilizes an intracavity sample cell and a circuit that provides low noise stable excitation and maintenance of a radio frequency (rf) driven gas discharge within the sample cell and a direct current output proportional to the if driving voltage, associated monitoring devices and software. When an optical stimulus interacts with the discharge, any electrical change in the discharge can be simply determined with high precision and accuracy by measuring the impedance of the discharge via a measurement of the direct current output. In a preferred embodiment the rf gas discharge is created with a series resonant oscillator with two push pull sections connected together to generate the high voltage signal. A current source provides a low noise stable current to power the oscillator sections. A band pass amplifier filters the current of the discharge prior to measuring it.
