In the fluorescent X-ray determination of chloride in titanium sponge, the particle size of sample was brought to pass through 50 mesh sieve with special care not to alter content of impurities. It was press-molded under rigidly controlled conditions, and chloride was determined on the fluorescent X-ray intensity of Cl-Kα line by the calibration method. Although it is generally said that the favorable particle size of sample is 200 mesh or less, the authors found that, in case of titanium sponge, 50 mesh under was a satisfactory fineness for obtaining sufficient accuracy and reproducibility. The determination of chloride in titanium sponge containing 0.07% chloride gave a standard. deviation of 0.0021%. An analysis required about 20 minutes including time for the sample preparation.
