External links. Therefore, the temperature of the prism and the temperature of the sample have to be controlled with high precision. In the infrared wavelength range several absorption maxima and fluctuations in the refractive index appear. These are used for fast sample exchange in quality control applications. Refractometers are often used in pharmaceutical applications for quality control of raw intermediate and final products. Due to the dependence of the refractive index on the wavelength of the light used (i.e.
The sample changer is controlled by the refractometer and assures fully automated measurements of the samples placed in the vials of the sample changer for measurements. Refractometer products and functions . In Automobile Industry keeping, a refractometer is used to measure the Coolant Concentration and Ph Value of the Coolant Oils for CNC Machining Process. Measuring combination of an automatic refractometer and a density meter as widely used in the flavors and fragrances industry - Source of image: Anton Paar GmbH, www.anton-paar.com . The refractive index of a given sample varies with wavelength for all materials. Qualification Plan (QP) Design Qualification (DQ) Risk Analysis Installation Qualification (IQ) Operational Qualification (OQ) Check List 21 CFR Part 11 / SOP Performance Qualification (PQ) . Gemstone refractometers are available both as classic optical instruments and as electronic measurement devices with a digital display.. This dependence of the reflected light intensity from the incident angle is measured with a high-resolution sensor array. Due to focusing light to a spot at the prism surface, a wide range of different angles is covered. In beekeeping, a refractometer is used to measure the amount of water in honey.
