Spectrochemical Analysis in the Vacuum Ultraviolet (VUV) with the Hollow-Cathode Light Source—II. Quantitative Analysis

Abstract

The use of a cooled hollow-cathode light source of new design was investigated for quantitative spectrochemical analysis of iodine in the vacuum ultraviolet (VUV). The conditions of the discharge and all prerequisites were tested, taking into account many possible sources of error. The results, shown in Tables and in graphs, indicate that this kind of light source gives good results for spectrochemical analysis in the VUV, for elements having the most sensitive lines in this spectral region. The range covered in this investigation lies between 1 and 100 μg iodine in a 1-mg potassium chloride matrix.
