Atomic absorption and atomic emission spectroscopy techniques are more widely used than atomic fluorescence spectroscopy. Stationary cold-vapor atomic absorption spectrometric attachment for determination of total mercury in undigested fish samples. Cold Vapor Atomic Absorption Spectroscopy. Determination of mercury by Cold-vapor Atomic absorption spectroscopy Conclusion Acknowledgment Atomic Spectroscopy Atomic-absorption (AA) spectroscopy uses the absorption of light to measure the concentration of gas-phase atoms. This method of analysis is capable of sequentially determining lead, antimony, and barium; however, in order to detect the low concentration of these species that may be present in GSR, the more sensitive flameless AAS techniques such as electrothermal atomization are required. Such techniques as flame, graphite furnace, hydride generation, and cold vapor are employed. Purpose/Objective: EPA’s Selected Analytical Methods for Environmental Remediation and Recovery (SAM) lists this method for preparation and analysis of water samples for compounds containing mercury. ESCA Electron Spectroscopy for Chemical Analysis; AAS Atom Absorption Spectrometry; AAS Atomic Absorption Spectrophotometry; ACEC Area of Critical Environmental Concern; DDS Design Data Sheet; AC Absorption Coefficient; HIRIS High Resolution Imaging Spectrometer; AWC American Wrestling Council; EXIF Exchangeable Image File Format; … Atomic absorption spectrometry (AAS) in order to get maximum analytical performance and measurement accuracy for mercury concentrations from 1 ppt (parts per trillion) to 100 ppm (parts per million). A mercury-vapor lamp is used as the UV light source, and the light is directed to the sample cell. The most common continuous atomizer in AAS is a flame, and the most common discrete atomizer is the electrothermal atomizer.
