Gas detection techniques have a fascinating history, dating back to the 19th century when canaries served as early warning systems for toxic gases in coal mines. When coal emerged as the Industrial ...

Micro-thermal conductivity detector (µTCD) gas sensors work by detecting changes in the thermal conductivity of the surrounding medium and are used as detectors in many applications such as gas ...

When it comes to working in facilities, safety needs to come first. Hazardous gases in the workplace can be a serious danger and lead to fires or explosions. Despite their dangers, not all gases can ...

Gas density is frequently estimated indirectly by gas pressure sensors. Because the pressure in a tightly sealed compartment fluctuates greatly with temperature, such systems require temperature ...

{mosimage} A gaseous mixture sample passes through a membrane into a measurement cell, which contains an optical light source and a microphone. Incident light modulated at a specific frequency is ...

A research team has developed wearable gas sensors that display an instantaneous visual holographic alarm. Gas accidents such as toxic gas leakage in factories, carbon monoxide leakage of boilers, or ...

Recent advances in the types of gas sensors available have created new opportunities for engineering smart products that can consider the air quality and smell, thus providing more information to ...

VOLATILE organic compounds (VOCs) are organic compounds characterized by their tendency to evaporate easily at room temperature. Familiar substances containing VOCs include solvents, paint thinner, ...
