Abstract
This thesis on the application of a light sensitive cell as a substitute for the human eye for the accurate adjustment of a colorimeter, had its origin in a class discussion two years ago, when Dr. Dvorak, then working on a quantitive colorimetric determination of adrenaline in blood, pointed out the exceeding difficulty of accurately adjusting the colorimeter where dilute or faintly colored solutions were to be measured. The possible use of some light sensitive cell, such as a selenium cell, in combination with a galvanometer, to determine when the instrument was properly adjusted, when the two fields of view were of the same intensity, was suggested. After a brief survey of the literature on the subject however, nothing further was done. Being interested in this application of a light sensitive cell I was permitted to pursue the work as a thesis project. The results of my efforts are given herein.
