Abstract: A narrow band-pass ultraviolet filter for continuous determination of protein consisting essentially of a first component (e.g., a concentrated solution of nickel sulfate and cobalt sulfate or red-purple ''''Corex'''' A glass) for absorbing substantially, or otherwise eliminating from consideration, all incident light in the visible region of the spectrum and a part of the light in the ultraviolet region of the spectrum, a second component (e.g., a concentrated solution of a heavy metal salt plus an acid addition salt of 2,7-dimethyl-3,6-diazacyclo-1,6heptadiene) which is a filter component for absorbing a substantial part of the light in the near ultraviolet region of the spectrum, and a separate third component for absorbing light of wavelengths below 260 millimicrons and a greater part of the light above 340 millimicrons, the separate third component consisting essentially of a complex compound of one or more metals (viz., Cr, Mn, Fe, Co, Ni, Cu or rare earth) and one or more chelating agents selected from the group consisting of ethylene-diaminotetra-acetic acid, iminodiacetic acid, nitrilotriacetic acid, diamines, and condensation products of diamines and carbonyl compounds. Components in solution form are enclosed in cells, the walls of which are transparent to ultraviolet light.
