    It is generally hard to determine the tungsten content by the fluorescent X-ray analysis with a tungsten target x-ray tube, because of the interference of scattered radiation of the primary x-ray., However, the scattered radiation can easily be eliminated by applying a filter before the window of the x-ray tube.Any ordinary x-ray fluorescent instrument has no attachment for fixing of the filter in operation.Therefore the filter is practically of no use.A primary beam filter which can be operated at the panel during the operating time of the x-ray tube was developed, and the determination of tungsten in high chromium-tungsten steel by a tungsten tube was successfully carried out with it.As a result, the daily analysis became facile and the accuriacy of measurements was improved.

    X-ray fluorescent analysis for thirty-seven elements (Mg, Al, Si, P, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Y, Zr, Nb, Mo, Ag, Cd, In, Sn, Sb, La, Ce, Hf, Ta, W, Hg, Pb and Bi) in iron, steel, iron ore, refractory bricks, slag, glass, coating materials on steel, aluminum and aluminum alloys was studied, and the influence of co-existing elements on the result of analysis of the above elements was summarized in two tables for the convenience of routine laboratory works; a table of elements whose fluorescent lines lie within +1°Cin angle from the fluorescent X-ray lines to be analized and a table of absorption edges of the interfering elements arranged in order of the wavelengths were prepared.With these two tables the effects of interfering elements and X-ray absorption were confirmed satisfactorily.
    It was found that, generally, the influence of neighboring lines is considerable when the concentration of the elements to be analized is low, and the effect of absorption due to nearly lines is considerable in the opposite case is high.
