Sentences with phrase «emission spectrometer»

The measured values reported on this web site were made using an atomic emission spectrometer, specifically an Inductively Coupled Plasma / Atomic Emission Spectrometer (ICP / AES).

Accurate determination of silver concentration requires the use of either an atomic absorption / emission spectrometer or a mass spectrometer.

Site survey tools included a panoramic camera, as well as a mini-thermal emission spectrometer that was supposed to search for signs of heat.

Most laboratories use either atomic absorption or atomic emission spectrometers because they are less expensive than a mass spectrometer (ICP / MS).

Not exact matches

Images from Cassini's ultraviolet imaging spectrometer (UVIS), obtained from an unusually close range of about six Saturn radii, provided a look at the changing patterns of faint emissions on scales of a few hundred miles (kilometers) and tied the changes in the auroras to the fluctuating wind of charged particles blowing off the sun and flowing past Saturn.

To verify emissions from the San Juan and Four Corners coal - fired power plants, the Los Alamos team deployed ground - based solar spectrometers and point sensors to measure atmospheric concentrations of gases at a site close to these power plants.

Since coming to PNNL, he has led or been significantly involved in studies of effects of surface heterogeneity on boundary layer structure, of mesoscale atmospheric flows induced or modulated by complex terrain, of the simulation of dust emission by wind erosion, and of the capabilities of a variety of atmospheric instruments — including a mass spectrometer and wind profiling radar — for measuring atmospheric turbulence.

Measuring with a spectrometer what is left from the radiation of a broadband infrared source (say a black body heated at 1000 °C) after crossing the equivalent of some tens or hundreds of meters of the air, shows that the main CO2 bands (4.3 µm and 15 µm) have been replaced by the emission spectrum of the CO2 which is radiated at the temperature of the trace - gas.
