Separation and Determination of Millimicrogram Amounts of Cobalt and Microgram Amounts of Copper in Biological Material

Abstract

THE chemical determination of metals chemically bound in biological material at concentrations less than 10−6 gm./100 gm. raises considerable difficulties. This is due to the fact that not all sensitive methods of determining metals in homogeneous material can be adapted to the treatment of samples containing organic compounds in the presence of an excess of other metals.
