The effect of the plasma composition on characteristics of the d.c. arc—IV: Influence of lithium on an arc in nitrogen
(Elsevier, 1971)
The radial temperature distribution of the arc burning in nitrogen was measured when a large quantity of Li2CO3 evaporates in the arc. In comparison to the radial temperature distribution of the arc burning in nitrogen ...
Direct solution analysis using an arc source incorporating two plasmas rotating in a graphite tube
(Elsevier, 1977)
As a continuation of earlier work on arc sources for the spectrochemical analysis of powdered samples, a source appropriate for multi-element analysis of trace elements in solution has been developed. The nebulized solution ...
The effect of the plasma composition on characteristics of the d.c. arc-II. Arc in argon and arc in nitrogen with water vapour
(Elsevier, 1971)
The experimental and theoretical curves of the radial temperature distribution of the arc burning in argon, are compared with the corresponding curves in nitrogen. The theoretical curves are obtained by solving the ...
The effect of the plasma composition on characteristics of the d.c. arc-III. Arc in carbon dioxide
(Elsevier, 1971)
The experimental and theoretical curves of radial temperature distribution of the arc burning in carbon dioxide, compared with corresponding curves in nitrogen, are considered. The theoretical curves are obtained by solving ...
A new type of d.c. arc as spectrochemical light source
(Elsevier, 1974)
A new type of d.c. arc light source for spectrochemical purposes has been developed. The horizontal arc burning in a graphite tube is placed in an inhomogeneous magnetic field. The limits of detection of In and Pb have ...
The effect of the plasma composition on characteristics of the d.c. arc - I General discussion of the effect of the chemical reactions
(Elsevier, 1971)
The influence of chemical reactions among the components of the arc atmosphere on the radial temperature distribution is discussed. Their effect on other arc plasma characteristics and the spectrochemieal determination of ...
Einfluß der Anionen bei spektrochemischer: Spurenanalyse im lichtbogen
(Elsevier, 1971)
The influence of the addition of ammonia into the arc plasma on the spectral line intensities (with background correction) of trace elements was studied. The intensity changes caused by addition of ammonium sulphate and ...
The effect of the plasma composition on characteristics of the d.c. arc - V The influence of iodine vapour on the radial temperature distribution of the arc burning in the atmosphere of nitrogen and argon
(Elsevier, 1971)
Considering the solutions of the Elenbaas-Heller energy balance equation it is possible to indicate how the chemical reactions among the components of added substances influence the radial temperature distribution in the ...
Powdered sample analysis in a double plasma arc source in a graphite tube
(Elsevier, 1977)
A double plasma d.c. arc burning in a horizontal graphite tube in a magnetic field was developed as a light source for spectrochemical purposes. It was demonstrated experimentally that a prolongation of the residence time ...
