X-Ray Fluorescent Analysis of Beryllium for Vanadium through Copper in the Periodic Table

Elements in the periodic table from atomic number 23 through 29, vanadium through copper, are determined from 0.0025% to 10.00% in beryllium metal and compounds convertible to beryllium oxide. Metal samples are dissolved in hydrochloric acid, evaporated to dryness, and oxidized at 900° O. The beryllium oxide is combined in equal portions with boric acid and pelletized. A fixed-time-variable-count method is used to obtain values for establishing analytical curves from which concentrations of samples are read.
