  • Beschreibung: <jats:p>1. Combinations of different counting systems have been investigated for their efficiency in assaying mixtures of<jats:sup>24</jats:sup>Na and<jats:sup>42</jats:sup>K. The advantages of a combination of thin and thick walled liquid G.M. counter tubes of the Veall pattern are described. Physical methods are unreliable when only a small proportion of the counts is derived from one isotope.</jats:p><jats:p>2. The separation of potassium by precipitation with sodium tetraphenylboron is described. Methods dependent on chemical separation are reliable even when<jats:sup>42</jats:sup>K makes only a small contribution to the counting rate of a mixture.</jats:p><jats:p>3. The application of these methods to the simultaneous measurement of exchangeable sodium and potassium is discussed and a rapid method for carrying out these measurements is described.</jats:p>
