FIELD: chemistry.
SUBSTANCE: method of determining a gel point by oscillatory viscometry includes placing a gelling solution into measuring vessels with different diameters, initiating the process and continuously measuring mechanical resistance of the solution in both vessels, plotting the obtained rheological curves on the same graph and determining the gel point from the graph as the region of divergence of the obtained curves.
EFFECT: higher measurement accuracy and more objective determination of a gel point by using cells of different sizes.
