INTERFERENCE COMPENSATED PHOTOIONIZATION DETECTOR |
摘要 |
An integrated sensor of volatile organic gas can include a photoionization detector (PID) and one or more additional detectors such as an infrared detector, a catalytic combustion detector, or an electrochemical detector. One embodiment includes a methane detector that allows correction of the PID measurements for the interference of methane with the PID and/or allows a combination of measurements of the sensors to measure a total hydrocarbon concentration. A further sensor of non-hydrocarbon quenching gases such as carbon dioxide may also be used in correction of the PID measurements. |
