RI Measurement of Solids, Semi 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. Refractive Index might be measured on incoming materials or finished products. Highly accurate measurements are possible with the right refractometer and a method to measure […]
Density Meter – Refractometer Instrument Combinations
Versatile Density Meter – Refractometer Instrument Combinations from Rudolph Research Analytical. Combined Density Meter – Refractometer Instrument Combinations Many users need to measure both refractive index and density and feel that a combined system will be a good alternative. The advantages of such a system are many; Since parts are shared the total cost of […]
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, […]

Specific Rotation Equation vs Optical Rotation
Specific Rotation Equation vs. Optical Rotation – What’s the Difference? By Angelo DePalma, PHD Polarimetry using Polarimeters measure the degree of rotation of polarized light as it passes through an optically active material. If you’re learning about Polarimetry you might come across the terms specific rotation and optical rotation. What is the specific rotation equation […]
