Google Patents US20120169237A1 - Hollow cathode lamp elapsed time recording system Atomic absorption spectrometry can be used in qualitative and quantitative analysis.US20120169237A1 - Hollow cathode lamp elapsed time recording system Ītomic absorption spectrometry has many uses in different areas of chemistry such as clinical analysis of metals in biological fluids and tissues such as whole blood, plasma, urine, saliva, brain tissue, liver, hair, muscle tissue. They were led by Sir Alan Walsh at the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Division of Chemical Physics, in Melbourne, Australia. The modern form of AAS was largely developed during the 1950s by a team of Australian chemists. AAS can be used to determine over 70 different elements in solution, or directly in solid samples via electrothermal vaporization, and is used in pharmacology, biophysics,Ītomic emission spectroscopy was first used as an analytical technique, and the underlying principles were established in the second half of the 19th century by Robert Wilhelm Bunsen and Gustav Robert Kirchhoff, both professors at the University of Heidelberg, Germany. In analytical chemistry the technique is used for determining the concentration of a particular element (the analyte) in a sample to be analyzed.
