Abstract : The report summarizes the investigations which were carried out to achieve increased spectrographic sensitivity for trace elements in high purity materials. Direct excitation of samples with the d.c. arc in air and in gaseous atmospheres was investigated. The reaction of chlorine on metal samples of Sn, Ga, and In to concentrate impurities was carried out. Also, an approach where the impurities were released from a molten metal sample was tried.
