The Direct Determination of Ethyl Alcohol in Saliva without Distillation. ∗

Abstract

Summary

All but a small, but relatively constant, quantity of the oxidizable material of normal saliva may be removed by the addition of 2 reagents: (1) a solution of C_uSO₄, H_gSO₄, and ferric sulfate, and (2) a suspension of Ca (OH)₂. The residual material from normal saliva is equivalent to 10.5 ± 4.6 mg. 70 of ethyl alcohol.

A procedure for the direct determination, without distillation, of ethyl alcohol in saliva is described. The results are 11.2 ± 3.3 mg. % higher than by the method of Friedemann and Klaas.
