Abstract

Abstract Samples from a number of individual liquid specimens containing varying and unknown amounts of insulin are made radioactive and are sequentially supplied to a continuously moving paper strip to impregnate the strip with separate spaced specimens along its length, which are then washed and dried. Cellophane tape is continuously adhesively united to the strip bearing the impregnated and dried specimens and the composite strip and tape are stored in a roll from which the strip may be taken for examination and analysis of the separate specimens.
