Refractive Index Measurement: Abbemat Heavy Duty Line

The Abbemat Refractometers from the Heavy Duty line are designed for measuring the refractive index in harsh environments and for special applications.

All Abbemat Heavy Duty refractometers are designed to withstand rough conditions they have a hermetically sealed stainless steel casing and are controlled by an external PC. This can be placed away from the workbench in another part of the laboratory. The Abbemat can be placed on its side to prevent sedimentation and disturbance affecting the results.

All Abbemat Heavy Duty refractometers provide full compliance with 21 CFR Part 11, with user levels, audit trail, and forgery-proof data export. Anton Paar also provides a qualification documentation package (IQ/OQ/PQ).

Why measure the refractive index?

The refractive index of a pure material is a physical property and can be used to identify and characterize materials. The refractive index measurement is easy, fast, non-destructive and independent of viscosity.

The refractive index of a dissolved substance in a solvent correlates with its concentration. Even quality control of multi-compound mixtures of a given mixing ratio can be undertaken by means of a refractive index measurement. Therefore a wide range of scales as well as a wide range of QC applications can be derived from this measuring technology.
