Application Specific LC System
Reducing Sugar Analysis System
-
The Nexera reducing sugar analysis system uses Shimadzu’s unique post-column boric acid-arginine fluorescence derivatization method. Unlike the refractive index detectors and evaporative light scattering detectors (ELSD) commonly used for sugar analysis, this system reduces the effects of impurities and offers both high sensitivity and a wide dynamic range. As a result, sugars contained in samples can be analyzed simultaneously, without dilution even when there are significant concentration differences.

UV Index Measurement
-
The sglux UV-Index sensors measure the UVI with a worldwide unique low measurement uncertainty of less than 5 %. This makes our sensors compliant to the highest measurement precisions class one according the DIN/EN 5031-11, chapter 8. Since 2018 our product UV-Cosine_UVI (ERYCA) is appointed for public authority tasks: The German Federal Office for Radiation Protection (BfS) services 27 measurement points in Germany for public information of the daily UV-Index. Twenty of these points (Andernach, Chieming, Duderstadt, Fichtelberg, Genthin, Giessen-Wettenberg, Schauenburg-Kassel, Langen, Lueneburg, Munchen-Neuherberg, Norderney, Belm/Osnabrueck, Schauinsland, Tholey, Todendorf, Waldhof-Falkenstein, Waldmuenchen, Wurmberg, Zingst and Zirchow) use the sglux ERYCA to obtain the local UV-Index value. In 2017 ARPANSA (Australian Government’s primary authority on radiation protection and nuclear safety) began replacing the existing biometers with SiC photodiode UV sensors (sglux ERYCA) at all network sites. There are currently thirteen measurement sites in Australia that have been upgraded to the new sensors.
