Abstract

A photoelectric recording colorimeter, with a very stable light source, is described. Provision is made for thermostatic control of the solutions being measured. The colorimeter was specifically designed for measurement of trace quantities of iodine (0.001 to 0.5 microgram in 5 ml. of solution). The types of records given by interfering substances are shown. © 1950, American Chemical Society. All rights reserved.
