Disclosed is a method for analyzing a sample solution, including introducing a sample solutionthrough a sample introduction partand developing the sample solutionto a developing layerthrough a capillary phenomenon to analyze an analyte contained in the sample solution, the sample introduction partbeing provided on one side of a test stripand the developing layerbeing provided on the other side of the test strip, wherein the test stripis disposed in such a development posture that the downstream region of the developing layer faces downward during the development. By this method, the developing rate is less susceptible to the viscosity of the sample solutionand thus has a small difference even among sample solutionsdiffering in viscosity. As a result, the analytical accuracy and reliability can be improved.

By measuring a luminance difference between predetermined two points or a luminance variation in a predetermined region in a state in which a liquid sample is developed in a chromatography specimen, and comparing the luminance difference or the luminance variation with a preset reference value, it is possible to automatically detect degradation such as a decrease in hydrophilicity in the lower portion of a liquid-impermeable sheet materialduring a chromatography inspection, thereby enabling an accurate inspection.
