New Rosemount™ 628 Universal Gas Sensors add carbon monoxide and oxygen depletion to the list of measurable hazards SHAKOPEE, Minn., (July 8, 2019) — Emerson has introduced two new Rosemount 628 Universal Gas Sensors to measure carbon monoxide and oxygen depletion in addition to the existing capability to monitor hydrogen sulfide.

While the choice of gases is limited for hard wire detectors they can be an economical choice when available. In general, the use of a transmitter is preferred for distances over 300' to 500' to simplify calibration. Sample Draw Detectors. Sample draw detectors have an integral pump, which draws the surrounding air to the detector.

Ethylene oxide sterilization is widely used in the field of sterilization of medical devices. Due to the advantages of active ethylene oxide gas, strong bactericidal power, wide bactericidal spectrum and slight damage to articles, the mixed gas of ethylene oxide and carbon dioxide has become one of the most important daily low-temperature sterilization methods.

Apr 05, 2018The carbon cycle in soil is a dynamic balance between photosynthesis, the respiration of decomposing organisms, and the stabilization of carbon. Soil stores at least three times as much carbon (in SOM) as is found in either the atmosphere or in living plants. The total global carbon stock in soil is about 2500 Pg C, including approximately 1550 ...
