Techniques used include atomic absorption, spectrophotometry, selective electrodes, pHmetro, conductivity, Soxhlet extractor, and the Kjeldahl method.
12.
Lower concentrations of sodium may be determined by atomic absorption spectrophotometry or by potentiometry using ion-selective electrodes.
13.
Atomic absorption lines are observed in the solar spectrum and referred to as Fraunhofer lines after their discoverer.
14.
Mr Frew worked closely with Alan Walsh, the originator and developer of the atomic absorption method of chemical analysis.
15.
At Imperial College, he created a new research group to work on analytical atomic absorption and atomic fluorescence spectroscopy.
16.
But by about 1975, electronic instruments such as atomic absorption spectrophotometers had made analysis of the steel much easier and faster.
17.
:ISO 8691 is about Petroleum products-- Low levels of vanadium in liquid fuels-- Determination by flameless atomic absorption spectrometry after ashing.
18.
The sputtered atoms, now in the gas phase, can be detected by atomic absorption, but this is a comparatively rare strategy.
19.
There he developed the innovative technique of using atomic absorption spectra, rather than atomic emission and molecular absorption spectra, in spectrochemical analysis.
20.
This acquisition marked the beginning of the research and development of analytical systems in the area of atomic absorption spectrometry and molecular spectroscopy.
