Potassium in submilligram‐size samples of mica was satisfactorily determined by a thin‐specimen, X‐ray emission technique. The method utilizes Ti in the sample as an internal standard and involves the determination of the ratio KKα/TiKα. The technique provides a rapid and accurate means of determining K as a function of sample treatment, provided that the Ti content of the sample does not change.
