Highly sensitive and selective SO 2 MOF sensor: the ...

These very promising results prompted us to evaluate the stability of the MFM-300 (In) MOF capacitive sensor for SO 2 detection at room temperature using reproducibility tests. In these tests, we explored the performance of the sensor in detecting two concentrations of SO 2, 500 and 1000 ppb, over a testing period of more than three weeks ().The results clearly showed that the detection levels ...

Does the CO sensor have a cross-sensitivity to H2?

Up to15%cash back· The electrochemical CO sensors used in the majority of our products do have a cross-sensitivity to elemental hydrogen (H 2) gas, with the precise degree of cross-sensitivity depending on the model in those applications where the CO monitoring is necessary in the presence of H2, models with CO-H sensor would be the best option.

At the heart of gas detection systems DRÄGERSENSOR®

Dräger has developed an organic electrolyte on a polycarbonate basis. Thanks to their better signal-to-noise ratio, these sensors can detect extremely low gas concentrations in the 10 ppb (parts per billion = 1:1,000,000,000) range. What is more, the sensors show less cross sensitivity to standard toxic gases which can be present in very low con-

the cross-sensitivity to CO2 and H2O. By incorporation of a diffusion-limiting porous barrier over one of the electrodes, it should be feasible to force the response of the sensor to be linear versus the H2 concentration. Conclusions and Future Work A H2 safety sensor has been demonstrated with an integrated, self-heated design operating at 430 -

Harmful Gas Recognition Exploiting a CTL Sensor Array

Oct 09, 2013· These sensor systems is often named “electronic noses”. An electronic nose usually consists of a cross-sensitivity sensor array and related data processing modules. With an appropriate pattern recognition algorithm, the sensor system has ability to smell and identify several harmful gases in a complex environment.

OSA | Silicon photonic dual-gas sensor for H2 and CO2 ...

Abstract. We report a silicon photonic dual-gas sensor based on a wavelength-multiplexed microring resonator array for simultaneous detection of H 2 and CO 2 gases. The sensor uses Pd as the sensing layer for H 2 gas and a novel functional material based on the Polyhexamethylene Biguanide (PHMB) polymer for CO 2 gas sensing. Gas sensing experiments showed that the PHMB-functionalized …
