A spectrographic method was developed for the determination of 18 trace elements in lanthanum, cerium, praseodymium, neodymium, and samarium compounds. The concentrations of the impurities cover 0.5 to 500 ppm. Most of these impurities are determined by the carrier distillation method. Several more refractory elements have been determined by total burning of the sample with a d- c arc ' or by the conducting briquet excitation technique with a high ' voltage condensed spark. The work has been carried out with a Hilger Automatic Quartz Spectrograph. (auth)
