Oil and gas engineers tasked with accurately measuring hydrogen sulfide (H 2 S) levels in both production and refining operations will want to know more about the all-in-one CA900 Sulfide Analyzer ...

For the first time, researchers at Washington State University have created an injectable compound or "probe" that illuminates hydrogen sulfide and hydrogen polysulfides in different colors when they ...

Chemists have developed a selective probe that detects hydrogen sulfide (H2S) levels as low as 190 nanomolar (10 parts per billion) in biological samples. They say the technique could serve as a new ...

Biochemists think hydrogen sulfide is an important gaseous biological signal. Studies have suggested that the molecule protects against oxidative stress and modulates brain activity. But there are few ...
