“…Instruments have been developed previously for the direct, photoelectric measurement of light intensity at several wave lengths simultaneously (3,4,6,10). These instruments, known as Quantometers or "direct readers," use the electric spark source and are capable of determining 20 or more elements in one sample.…”

The results for the determination of copper in aluminum are shown in Table 11. Two 1.000-gram samples each of the German standard and British chemical standard 198a were dissolved and extracted directly. For the BCS 198a, all results were higher than the certificate value 0.003.The procedure for extracting the copper( I)-neocuproine complex is the same for solders and aluminum alloys. The procedures for dissolving the samples and keeping salts in solution piior to the extraction are specific for different alloys.The method has been tested in the range 0.0017 to 0.3% for copper in aluminum standard sampled and 0.004 to 0.4% copper in solder standard samples.A4 high concentration of aluminum was found to prevent the complete extraction of copper by neocuproine. The addition of hydrofluoric acid remedied this interference. When sodium fluoride \vas added instead of hydrofluoric acid, extraction of the copper complex was not complete.

“…Spectacular instruments including many of the above operations are being manufactured {12, 22,42,50,66,204,212,262,451,452,523,536). They cut the time required for an emissimetric analysis to a matter of minutes or even seconds, thus surpassing the wildest dream of the analyst.…”
