An adjustable atomizer for atomic absorption spectroscopy

Journal of Scientific Instruments, 1965
A pneumatic atomizer is described in which the position of the capillary in the venturi is adjustable to 0.0005 in. or better, so that the uptake of liquid and the characteristics of the spray can be controlled. The design allows ready interchange of different sizes of capillary and venturi.

Enhancement of the atomic absorption signal by silicate at electrothermal atomic absorption spectrometry

Analytica Chimica Acta, 2000
Abstract Effects of silicate on the atomic absorption of 26 elements were studied. It was found that the atomic absorption signals of aluminum, beryllium, chromium, gallium and molybdenum were enhanced in the presence of silicate by the factor of 3.13,16.1, 2.17, 23.1 and 1.25, respectively. The optimum silicate concentrations were 10–20 μg ml −1 Si(

Absorption of Light by Atoms in Solids

Physical Review, 1956
The interactions of an atom with its neighbors in an idealized solid are taken into account explicitly in treating the absorption of light, as contrasted with the usual introduction of an "effective" field and mass. In the discussion of the magnitude of the absorption coefficient, two cases are treated: one, the absorption by an impurity atom, in which

Atomic absorption spectroscopy. Stagnant or pregnant

Analytical Chemistry, 1974
WHEN Foil Miller invited me to participate in the Silver Anniversary Symposium on Great Moments in Analytical Chemistry, he suggested that I may care to indulge in some personal reminiscences and comments regarding the development and present status of atomic absorption spectroscopy.

Multielement Atomic Absorption with a Continuum Source

Analytical Chemistry, 1986
The emerging technique of multielement atomic absorption with a continuum source is reviewed and discussed. The advantages of this technique over single-element atomic absorption are addressed.
