Sample solution preparation method, measurement cell, measurement kit, and sample solution preparation device

A sample solution preparation method, a measurement cell, a measurement kit, and a sample solution preparation device are disclosed for measuring a target compound contained in food by an immunity analysis method using fluorescence. The present disclosure features including a dialysis step for bringing a target compound-containing solution that includes the target compound into contact with a dialysis fluid through a dialysis membrane to transfer the target compound to the dialysis fluid, in which the molecular weight cut-off of the dialysis membrane is within a range of 2*102 to 2*105, and the volume of the dialysis fluid is relatively smaller than the volume of the target compound-containing solution. 一种用于通过使用荧光的免疫分析方法测量食品中包含的目标化合物的样品溶液制备方法、测量单元、测量试剂盒和样品溶液制备装置。本公开的特征包括：用于使包括目标化合物的含目标化合物溶液通过透析膜与透析液接触以将目标化合物转移到透析液的透析步骤，其中透析膜的截留分子量在2×102至2×105的范围内，并且透析液的体积相比于含目标化合物溶液的体积相对更小。
