TDLAS is often dubbed a workhorse. In contrast, CRDS requires a more complex, laboratory-grade setup and more complex data ...

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 following discussion presents a case history of how a new state-of-the-art seismic processing technology, wavelet energy absorption (WEA), is used in the direct detection of hydrocarbons in a ...

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 ...
