Abstract

822,447. Photo-electric fluorescence meters. HARRISON, W. Nov. 7, 1957 [Nov. 12, 1956], No. 34456/56. Class 40 (3). Apparatus for determining the fluorescence of a sample S in ultra-violet light comprises alternative sources; mercury discharge lamp DL and filament lamp FL with associated lenses L1, L2 and ultra-violet filters UV1, UV2, and a photo-cell P connected to a galvanometer, the light falling on the photo-cell being varied by filters F1, F2, F3, &c. mounted on a rotatable wheel W. Specification 787,589 is referred to.
