We propose a method to measure a subdiffusion coefficient Dα. The method, which exploits a membrane system, relies on the so-called near-membrane layers. We experimentally study the diffusion of glucose and sucrose in a gel solvent. We find a fully analytic solution of the fractional subdiffusion equation with the initial and boundary conditions representing the system under study. Confronting the experimental data with theoretical results, we find the values of the subdiffusion coefficient for investigated substances.
