Apr 04, 2017It is convenient for target gas detection. In this study, we developed the compact Raman lidar for hydrogen gas detection. To prevent the explosion accident of hydrogen gas, the sensor should detect the target gas of the low concentration of 1/4 of the explosion limit. In the case of hydrogen gas, its concentration is 1% [6, 7, 8]. The optical ...

Most detectors produce an audible or visual indicator, such as an alarm or series of lights, to signify high levels of gases in a particular area.

Jul 23, 2020Methane Detection and Monitoring What is the health and safety problem? The use of machine-mounted methane monitors is required by federal regulations to alert miners to the presence of potentially dangerous concentrations of methane while mining coal. The monitors must be permanently mounted on a mining machine to provide continuous readings of methane levels near a working face.

Carbon supported phosphoric acid (H3PO4/C) was found to be a more productive catalyst for the gas-phase synthesis of the diesel fuel additive/substitute oxymethylene ethers (OME) as compared to benchmark zeolite catalysts. In this contribution, the performance of catalysts H3PO4/C and related H2PO4−/C and HPO42−/C materials in OME synthesis from methanol and formaldehyde is described.

Sep 20, 2018Natural gas is lighter than air and will usually dissipate rapidly in the outside environment. Inside buildings, however, it tends to collect, particularly in attics and dead air spaces.

But the most sensitive tracer gas method—helium mass spectrometry in a vacuum chamber—can detect leaks as slow as 1 × 10–12 cm3/sec. There are several reasons why tracer-gas methods are able to detect much smaller or slower leaks: • The testing equipment is highly sensitive and can detect minute levels of the gas.
