Abstract
A method for decreasing the atomic-absorption sensitivity of calcium by using the overlap of the germanium 422·657 nm non-resonance line profile with the calcium 422·673 nm resonance line profile is described. Almost linear calibration graphs were obtained with concentrations of up to 1500 µg ml–1 in the air-acetylene flame (sensitivity 8·3 µg ml–1), and up to 1000 µg ml–1 in the nitrous oxide-acetylene flame (sensitivity 6·0 µg ml–1).Keywords
