Abstract

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°C. 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.
