Quantile regression with a metal oxide sensors array for ...

· Experimental data from 6 MOS gas sensors and a methane FID analyser taken during fourth months have been used for that purpose. The data processing consisted of (i) a drift correction, (ii) the addition of interactions, (iii) a principal component analysis (PCA) to extract new uncorrelated predictors, and (iv) a log transform of the methane data distribution. The forecast ability of the ...

CyclicVoltammetryBased SolidState Gas Sensor for ...

principle; for that purpose, we have limited the environmental exposure of the sensor to N 2 in order to better confirm the origins of the observed signals. In that configuration, we have exposed the sensor to two concentrations of methane in order to observe its linear response, and we have compared the methane signal to a signal obtained during detection of CO to prove its speciation ...

Photoionization detector Wikipedia

Principle. In a photoionization detector highenergy photons, typically in the vacuum ultraviolet (VUV) range, break molecules into positively charged compounds enter the detector they are bombarded by highenergy UV photons and are ionized when they absorb the UV light, resulting in ejection of electrons and the formation of positively charged ions.

Pololu Methane Gas Sensor MQ4

This methane gas sensor detects the concentration of methane gas in the air and ouputs its reading as an analog voltage. The concentration sensing range of 300 ppm to 10,000 ppm is suitable for leak detection. For example, the sensor could detect if someone left a gas stove on but not lit. The sensor can operate at temperatures from 10 to 50°C and consumes less than 150 mA at 5 V. Please ...

Development of Gas Sensor Array for Methane Reforming ...

The article presents a new method of monitoring and assessing the course of the dry methane reforming process with the use of a gas sensor array. Nine commercially available TGS chemical gas sensors were used to construct the array (seven metal oxide sensors and two electrochemical ones). Principal Component Regression (PCR) was used as a calibration method.
