Cross sensitivity of toxic sensors: Chris investigates the ...

· Cross sensitivity responses will vary from sensor type to sensor type, and suppliers often express the cross sensitivity in percentages while others will specify in actual parts-per-million (ppm) levels. Cross sensitivity is a sensor’s reac­tion to other gases which can “interfere” with how the sensor reacts. Exposing a sensor to a gas that is not the target gas can cause an undesirable effect; …

Electrochemical sensors cross sensitivity - Big Chemical ...

Electrochemical sensors cross sensitivity Experimental studies have also shown that selective detection is an important advantage of an electrochemical sensor, but sometimes their responses are affected by the presence of other gases (Park et al. 2003). As established in numerous experiments, cross-sensitivity is often observed when lype II or Type III potentiometric sensors are exposed to …

Introduction to Electrochemical (EC) Gas Sensors

2O → CO 2+ 2H+ +2e-Counter Electrode: ½O 2 + 2H+ + 2e-→ H 2O Overall: CO + ½O 2 → CO 2 Because the electrodes have a finite catalytic activity (which can change with time and temperature) it is necessary to limit the rate of diffusion of target gas into the sensor (using a barrier) to ensure the gas is efficiently reacted. This barrier takes the form of a small hole or capillary in the ...

Carbon Monoxide and Sensory Sensitivity

· How does CO cause multi-sensory sensitivity? The public (and most doctors) are taught only that CO is an invisible, odorless and tasteless gas that can kill you in seconds at very high levels of exposure. But few know that CO at low levels is also vital for human life. We and all other mammals produce CO constantly in the normal breakdown of our heme proteins (such as hemoglobin in red …

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

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 question. For those applications where the CO monitoring is necessary in the presence of H2, models with CO-H sensor would be the best option.

Why is hydrogen such a big issue for CO sensors? | GfG ...

The reason that CO sensors are potentially susceptible to hydrogen (H2) interference is the reaction that is used to detect gas. Hydrogen is actually part of the detection reaction. The relative response to hydrogen depends on the brand and model of sensor. Some commonly used CO sensors show a relative response to hydrogen as high as 60%. (Not GfG sensors, of course!) Sometimes the cross sensitivity …
