ABSTRACT:
An apparatus for automatic quantitative analysis of specimens of a blood serum by a cataphoretic process comprises a supply of a clearing liquid which is supplied to a film on which a plurality of specimens are disposed at a constant pitch, light source means for projecting light onto the film which has been made clear by the application of the clearing liquid thereto, measuring means including a photoelectric transducer element which receives and determines the light which has transmitted through the film, feed means for intermittently feeding the film so as to locate it at a measuring port which is positioned between the light source means and the photoelectric transducer element, and scan drive means for displacing the light source means and the photoelectric transducer means crosswise of the film to scan a particular one of the specimens which is positioned at the measuring port each time the film comes to a stop. In this manner, the film carrying the specimens is made clear by the clearing liquid, and a quantitative analysis is made by scanning the individual specimens by the photoelectric transducer element in the course of the intermittent feed of the film, all in an automatic manner.
