Determination of Carbon 14 in Fatty Acids by Direct Mount Technic. *

Abstract

Summary

It is demonstrated in the present investigation that the C¹⁴ activity of a fatty acid sample can be readily determined by a direct procedure that avoids the dilution of activity and laboriousness associated with the preparation of BaCO₃ mounts. The simplicity of this new procedure permits a single operator to mount as many as 50 samples in 8 hours with an error of reproducibility not in excess of 5%. By means of an empirically constructed curve, the observed activities can be converted to a BaCO₃ basis.
