In order to determine the trace amounts (3 ng–100 ng) of lanthanoids in chondritic meteorites, new and convenient analytical procedures of radiochemical neutron activation method were presented. Applying these procedures to Antarctic meteorites, a total of ten lanthanoids (La, Ce, Nd, Sm, Eu, Gd, Tb, Tm, Yb, and Lu) were precisely determined in a sample of 50–100 mg. Considering several error sources such as counting statistics, collection of interferences, and determination of chemical yield, magnitude of overall error was estimated for each element.
