ABSTRACT:
In a biochemical analysis apparatus a frameless dry chemical analysis film having a reagent layer formed on a support sheet is taken out from a cartridge storing therein a plurality of the frameless chemical analysis films, applied with a sample liquid, inserted into an incubator and taken out from the incubator and at least a part of these steps and film transferring steps between these steps is effected with the film held by a suction pad. A change of pressure in the suction pad when it attracts the film under a suction force is measured and the attracting state of the suction pad is judged on the basis of the result of the measurement. The part of the steps which is effected with the film held by the suction pad is controlled on the basis of the judgment.
