The process was simplified by measuring the concentration of the crystals in the solution by passing 2 - 3 MHz ultrasonic vibrations through the constantly stirred solution, and the concentration of crystals was determined from the absorption coefficient of ultrasonic vibrations.deinfo:eu-repo/semantics/openAccessKristallisation , Vitamin C540article2009-11-24
