The paper deals with accuracy of the diffusion coeffcient measurement. Diffusion coeffcients were measured by the pulse filed gradient spin echo (PFGSE) method. b-factor value as well as the diffusion coeffcients of the measured sample is dependent on the gradient field. As a result is presented relationship between diffusion measurement accuracy and changes of the magnetic field. Consequently, diffusion gradients were modified for the highest accuracy of the measurement. As a specimen by the nickel sulfate water solution filled syringe is used.
