Abstract : A mass spectrographic technique for the impurity analysis of potassium chloride by the high frequency spark source was evaluated. The technique proved to be successful but rather tedious. Because of the low ionization potential of K, the usual assumption of equal sensitivity for analysis of all elements is dubious and further work using internal standards is necessary. Zone refining of KC1 significantly reduces the concentrations of the impurities Na, Mg, Al, Si, S, Br, and Rb. The elimination of bromine by bubbling chlorine through the molten salt is very successful.
