A nondestructive method is described for determining microgram quantities of silver by analysis on a 256-channel pulse-height analyzer following activation in a nuclear reactor. (C.H.) 1782l A method is described for the determination of Cu in Be or BeO by extraction of the neocuproine complex with Methyl isobutyl ketone. The method is accurate to plus or minus 5% or plus or minus 2.5 micrograms of Cu, whichever is greater. The accuracy and sensitivity could be improved by appropriate choice of sample size, volume of extract and/or cell length. Of the 68 elements investigated, only Au interferes in 10 mg amounts; in this case a slight loss of Cu is caused by ooclusion or co- precipitation.
