Gas analysis has essential applications in research, development, and industry. Gas analysis instruments are typically used to determine the concentration of known gases in an environment or ...

Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

The basic principles of AAS can be expressed as follows. Firstly, all atoms or ions can absorb light at specific, unique wavelengths. When a sample containing copper (Cu) and nickel (Ni), for example, ...

The Robur RTAR is a modular, reversible cycle gas absorption heat pump system capable of producing hot water up to 140°F and chilled water down to 41°F. Under nominal conditions, each heat pump module ...

Researchers have developed a method for quickly detecting and identifying very low concentrations of gases, which, could form the basis for highly sensitive real-time sensors for applications such as ...

The microseepage of gaseous hydrocarbons often creates a soil atmosphere containing lighter hydrocarbons (C1-C5). The gases in the soil may be sampled and analyzed to determine the specific mix of ...
