SPECTROPHOTOMETRIC DETERMINATIONS OF PURIFIED BILIRUBIN

Abstract

Spectrophotometric transmission curves of purified bilirubin (from Dr. Clarke, Eastman Kodak Co.), with a study of the effects of fading or increase of spectrophotometric transmission with time, and applications of the laws of Lambert and Beer, furnish additional evidence that the pigment with which the authors have dealt in previous publications on the sites of formation of bile pigment, experimental jaundice, etc., is one and the same pigment, namely, bilirubin.
