The Coleman Photofluorometer is the practical tool for routine fluo rescence analysis in the laboratory. Simple and easy to use, it has proved its value over years of use in clinical and control labora tories having a large number of routine analyses. Its sensitivity range covers all practical applications •—• quinines, quinoline, vitamins, porphyrins, steroids, metal complexes, etc. The instrument permits quantitative de termination of fluorophors (quinine, for example) down to 3 parts in 10 billion.
