A method is presented that is applicable to tungsten concentrations above about 0,1 per cent. Matrix variations are suppressed by a tenfold to fiftyfold dilution of the sample material during fusion, which eliminates any mineralogical effects and produces a clear glass disc that is used direct for intensity measurements. Residual matrix variations are compensated for by application of the background-ratio technique, and the intensity measurements are evaluated by comparison with synthetic standards, the calculation being done on-line by use of an Olivetti Programma 602 desk-top computer. An annotated computer programme is provided for calculation of the curve of the calibration graph and evaluation of the sample intensities. The method is rapid and has a coefficient of variation of 1,5 per cent at a level of 50 per cent tungsten when used under routine conditions. Comparison with the results of a wet-chemical method showed the proposed method to have no bias.

International Series of Monographs in Analytical Chemistry, Volume 47: Analytical Chemistry of Molybdenum and Tungsten describes the chemical and instrumental methods of analysis of molybdenum and tungsten. This book is composed of 15 chapters that particularly consider detailed methods for determining these metals in typical samples and their alloys by both classical and modern techniques. The opening chapters discuss the history, occurrence, physico-chemical properties, and applications of molybdenum and tungsten. The succeeding chapters deal with the metals’ sampling, decomposition, separation, and qualitative detection. Considerable chapters are devoted to various chemical and instrumental methods for their analysis, including gravimetry, titrimetry, colorimetry, polarography, amperometry, coulometry, emission and atomic absorption spectroscopy, X-ray spectrophotometry, mass spectrometry, and radiochemical methods. The concluding chapter examines the determination of impurities and alloying elements. This book will prove useful to analytical and inorganic chemists, as well as analytical and inorganic chemistry students.
