Abstract: An ink feed measuring device comprising a luminuous plate and a light receiving plate constructed so as to hold a photographic film of a printed matter between the two plates, the luminuous plate having one or more electro-luminescent plates and the light receiving plate having a plurality of photoelectric elements corresponding to the sectioned areas of the photographic film, wherein ink feed volume corresponding to each sectioned area of the photographic film is measured based on the amount of light transmitted through the sectioned areas of the film.

Abstract: According to the method of this invention, liquid or solid samples are first measured inaccurately with a pipette or some other measuring instrument and the measured sample quantity is weighed. After the addition of reagents, the samples are measured by the vertical principle and the results of this measurement are calculated with the weight results in a calculator which is programmed to calculate the analysis result in desired units.
