An object of the present invention is to provide a small-sized automatic protein quantification apparatus which has a small burden on an analysis worker, does not cause bacterial contamination in equipment of each process at the time of collecting a sample liquid, has a short measurement time, and has a small size. SOLUTION: Sampling for automatically collecting a sample liquid online from at least one or more processing steps of a cell culture step and a separation step of a plant for producing a protein by culturing living cells, or a purification step of a culture product. parts and, a preprocessing section for adjusting the liquid composition was performed at least one dilution or filtration sample liquid, has a cross-sectional area of 0.04 mm 2 or less, the protein antigen-antibody reactions involved in the adjusted solution A reaction unit for quantifying the protein by using the method, a measuring unit for quantifying the protein based on the result of the reaction, a control unit for automatically controlling a series of operations of the above-described device components, and a recording unit for recording the quantification result. .
