The American Instrument Company's Spectrophotofluorometer . . . T h e Aminco-Bowman Spectrophotofluorometer (SPF) is a highly sensitive and versatile instrument for the measurement of fluorescent properties of various compounds at ranges extending into the infrared regions. The complete operating unit includes: (A) Optical Unit; (D) Photomultiplier Microphotometer; and (C) Cathode-ray Oscillo graph. If permanent record is desired, a variety of recorders is available (one shown above as B).
The American Instrument Co., Inc., 8030 Georgia Avenue, Silver Spring, Maryland, has compiled a list of more than 200 compounds analyzed by the SPF which shows activation and fluorescence maximum wavelengths, pH, and ultimate sensitivity.
