An automatic analysis method of and apparatus for the full automation of an enzyme reaction analysis from the pretreatment step of the reaction to the data processing step, wherein the operation of the pretreatment step is arranged to be sequentially performed on many samples with full automation by the use of robots and computers to improve savings efficiency and measurement accuracy. Also, the pretreatment steps of weighing samples in many sample tubes, adding the given amount of solvent corresponding to the weighing value and placing the samples into the dissolution vessel to dissolve the sample in the solvent are adapted to be sequentially performed with full automation with the use of the robot, computer and electronic balance. Furthermore, the filtration, concentration and the injecting operations into the HPLC are automatically performed. The automatic apparatuses are coupled to each other so that the filtration, concentration, injecting operations are allowed to be sequentially performed with full automation using an on-line system.
