Studies on the Comparative Assay for the Alcohol Contents by the Determination of Alcohol Number and Diffusion Method

알코올수측정법(數測定法)에 의(依)한 알코올수(數)와 확산분석법(擴散分析法)에 의(依)한 에탄올 측정량(測定量)과의 비교연구(比較硏究)

A Diffusion analysis method is described for the determination of alcohol content in tinctures and spirits and then, the comparison test of the official alcohol number test with the diffusion analysis method has hen carried out. Throughout this experiments, a transformed Widmark apparatus is used. It is found that the diffusion analysis method using the transformed Widmark apparatus is very simple and occapy a small space. One of the most convenient fact is many sample can be analyzed at a time with this apparatus. Experimental data indicate that 95% of alcohol content obtained by the official alcohol number test is found in the diffusion analysis.
