How Refractive Index Solves Analytical Challenges Across Industry A modern refractometer measures refractive index. Concentration tables, custom scales, software, and controlled measurement conditions turn that one physical measurement into many useful analytical answers. One Instrument – Many Answers Walk into one laboratory and a refractometer may be used to measure Brix in a beverage. In […]

Measurement of Concentration Dependence of Refractive Index to Confirm Gel Permeation Chromatography Parameter
Measurement of Concentration Dependence of Refractive Index to Confirm Gel Permeation Chromatography Parameter Application Note November 2019 by Gabor Kiss Background: Gel Permeation Chromatography Refractometer One of the workhorse techniques for polymer characterization is Gel Permeation Chromatography (GPC) which is used to measure molecular weight, molecular weight distribution, degree of branching, radius of gyration, solvent […]
Refractometer Validation
Refractometer Validation Refractometer Validation – In a regulated laboratory the purchase price of an instrument is only relatively small part of the total cost. For some instruments there are expensive consumables and the manufacturer will provide the original instrument very inexpensively in order to lock the laboratory into these. For other instruments the manufacturer […]
