    The evaporation method developed by Mandel' shtam and Zaidel is applied for the determination of impurity elements in uranium oxide.For the evaporation of impurity elements, most favorable sam-ple temperature, duration of heating, sample weight, and gap length between a collector electrode and a crucible are chosen.Calibration curves for the determination of Fe, Cr, Mn, Ni, Cu, B, Si, P and Cd are prepared.In the analyses of B and Cd, AgCl is added to uranium oxide (1%) as a carrier before evaporation and a d.c.arc excitation (10A) is used in the spectrographic procedure.Though the repeatability of analytical results is 10% or so for each element, the values determined for Fe and Ni are considerably deviated from the values obtained by the carrier-distillation method and chemical analysis.The evaporation rate is measured as a function of evaporation temperature for Sb, Fe and Cd by the use of radioactive tracers 124Sb, 59Fe and 115mCd respectively.

    Alkaline and alkaline earth elements in biochemical materials can be determined flame-spectrochem-ically after they have undergone requisite chemical pre-treatment or dilution with water.Use of some oxidizing agent and acid, 30% hydrogen peroxide and concentrated nitric acid for example, is found adequate for the determination.
    Matched standard solution series can be made easily for these samples using Hitachi's Recording Flame Spectrophotometer;they give appropriate analytical results.A new type of oxy-propane atomi-zer burner and a filter flame photometer have been devised for routine use in hospital and other res-arch laboratories of medicine or biology.Some of their spectrochemical characteristics are described.
