Refractometry is a quick and reasonably accurate alternative to chemical analysis for serum total protein when a rapid estimate is required. The refractive index of water at 20°C is 1.330; if solute is added to the water, the refractive index of a dilute solution increases linearly and proportionally to the solute concentration ...
WebA digital refractometer measures the refractive index or related values of a liquid sample using the total reflection method. This measurement is done automatically, which reduces operator influence and enhances accuracy. Using a small sample volume (0.5 to 1 mL), highly accurate measurements of the index of refraction are performed in seconds.
