Detection of smallest amounts of dissolved compounds with little or no absorption in the UV-Vis spectral range still represents a chromatographic challenge today. Refractive Index Detection is in many cases the only viable choice in modern analytics.

The Refractive Index Detector, often simply called RID, is one of the most flexible tools available in HPLC, and a true work-horse for the detection of Saccharides, in particular. KNAUER OEM division expands the product portfolio with an RID kit that fits perfectly in this tradition. But with many innovative features which makes it unique on the today’s market. “It has always been important to us to re-invent known technologies with innovations and to continuously supply the best possible tools to the scientific community” says Dr. Marc Diener, head of KNAUER R&D about the current product.

KNAUER always delivers exclusively high quality technology made in Germany. For OEM Clients, the kit is easily adapted and fitted into customized housings to fulfill specific market requirements at favorable costs.

For more than 30 years KNAUER has been a reliable OEM supplier providing a strong supply chain and excellent support. KNAUER develops and manufactures exclusively in Berlin state-of-the-art pumps, detectors, valves, and further HPLC Components with long-term business relations to a number of major players in the HPLC field.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

The two major instrument classes are single-beam or double-beam spectrophotometers. More specialized equipment includes colorimeters, spectroradiometers and refractometers. Portable and microvolume spectrophotometers are also available. For the modular spectroscopy lab, explore a range of light sources for combination with a spectrograph/spectrometer and optics.

It is widely used in fields like biochemistry, pharmaceuticals, and environmental analysis. By exploiting differences in the interaction of substances with a stationary phase and a mobile phase, chromatography enables precise purification and quantification of compounds. Whether you're working with complex biological samples or industrial chemicals, chromatography is essential for obtaining high-quality results.
