The Windows program SORPVEJ collects weighing data from the balance and plots points on the sorption curve. The features of the program are: All data are transmitted automatically from the balance to the computer. Each point on the curve (upper right inset)is an original measurement and every time you get a new point on the curve the program calculates a new and better fit for the weight decrease. The equation (lower left inset) calculates new variables every time to make the curve smooth until equilibrium. The program decides when moisture equilibrium is reached. The program distinguishes between absorption and desorption. To ensure that the same procedure is used every time, guidance is build into the program.Keywords: Sorption curve, equilibrium state, program.
