The use of a non-dispersive atomic fluorescence spectrometer for the determination of zinc in soils and nonferrous metal alloys

Nonferrous metallurgy-light metals: aluminum, beryllium, titanium, and magnesium

“…Zinc was determined in Al alloys by Norris and West (202) using a nondispersive atomic fluorescence spectrometer. The detection limit was 0.5 µg/L in solution.…”

Inorganic and geological materials

“…Among more recent reviews is that of Massmann (118) which includes a survey of furnace methods in AAS, as does a recent review by Woodriff (203). The Third Theophilus Redwood Lecture, delivered by West (200), includes a survey of new developments in atomic fluorescence spectrometry; a review by Browner (31) contains more than 200 references to work in APS. Among interesting developments in atomic fluorescence spectrometry are the first reported applications of non-dispersive APS by Norris and West (135) for the determination of Zn in soils and alloys and by Tsujii and Kuga (188) for the determination of arsenic. The prolific school of analytical chemistry at the University in Birmingham has in recent years devised a new flame analytical technique which they have named Molecular Emission Cavity Analysis (MECA) and which appears to be extremely useful for determining trace amounts of many metals and nonmetals. The technique employs a small cavity at the end of a rod into which samples are deposited.…”

Determination of nickel by non-dispersive atomic fluorescence spectrometry using a graphite furnace atomizer and a high frequency discharge lamp.

“…Detec tion limits for about twenty elements including nickel were described by Larkins and Willis.6) The advantages and disadvantages of nondispersive atomic fluorescence spectrometry have been discussed by many workers. [5][6][7][8][9][10][11] According to the best of our knowledge, however, there has been no paper on the non dispersive atomic fluorescence spectrometric measurement of nickel using electrothermal atomization as well as on nickel determination in practical samples for either dispersive or non-dispersive modes. The difficulities seem to be that the high dissociation energy of nickel monoxide (4.2 eV) requires a high atomization temperature, which causes an significant increase of background noise level.…”
