Refractometers: The Fun and Efficiency of Personalization

by Angelo DePalma, PhD
Refractometer manufacturers quote accuracy and reproducibility to the fourth, fifth, and sometimes even the sixth decimal places. A good manufacturer will only advertise this level of accuracy after carefully running standards.

Versatile Analyzers, from QC to LC

by Angelo DePalma, PhD
Refractometry is thought to be a limited analytical technique that works best with binary solutions—for example, salt or sugar solutions—where it excels at precise concentration measurements.

Innovating Around the Edges

by Angelo DePalma, PhD
Refractometers are analytical instruments that measure the refractive index (RI) of liquids. Physicists define RI as the ratio of the speed of light in a vacuum divided by its speed through a test medium.
