RI Measurement of Solids and Films. RI measurement of solids and semi-solids is useful in labs for monitoring quality to insure consistency of transparency, pigmentation, or batch quality. RI might be measured on incoming materials or finished products. Highly accurate measurements are possible with the right refractometer and a method to measure the material. Instrument: […]
Refractometer Uses in Industry and Selection
Refractometer Uses in Industry and Selection By Angelo DePalma, PHD Refractometer uses: Characterizes fluids based on their refractive index –the refraction occurs due to the change in the speed of light as it travels through a material of one density to one of different density. By definition a vacuum has a refractive index of 1, […]

Refractometer Temperature Correction Vs Control
Refractometer Temperature Correction & Control Peter Marriott – Refractometer Product Manager Rudolph Research Analytical Also see video: Refractometer, Temperature Correction & Control with a Rudolph J457 We are going to look at the effects of changing temperature on refractive index measurement and if Temperature Correction can compensate for temperature variances or if actual temperature control […]
Digital Refractometers – Universal Concentration Meters
Digital Refractometers – Universal Concentration Meters By Angelo DePalma, Ph.D – Partial Reprint – Originally Published April 6th, 2011, for original see Lab Manager; – Refractometers are instruments that quantify and identify chemicals and materials based on their refractive index (RI). A unique property related to the speed of light as it passes through a substance, RI (Refractive Index) […]
