Abstract:

X-ray spectrochemical methods were developed for both solid and solution samples. Solid standards were prepared in an induction furnace or a small arc furnace. The standards were analyzed by wet chemical methods and by X-ray solution techniques. Analytical working curves were prepared for manganese bronzes, aluminum bronzes, and brasses using the Rock Island Arsenal secondary standards and available primary standards. Problems of short time instrumental drift were minimized by alternating samples and standards and averaging results. Problems in long time instrumental drift were solved by applying a mathematical computation method suggested by Loranger. Author
