The Hitachi LaChrom Ultra UPLC L-2400U UV detector specializes in fastest detection and extreme sensitivity. With extremely low detector response times of 10 ms, this detector can register even the narrowest and rapidly eluting peaks with high precision. It is based on the principle of the double beam photometer in conjunction with a rated monochromator and offers the highest possible sensitivity even with the fastest detector response times. Using the different spectral lines generated by the deuterium and mercury sources, wavelength calibration can be carried out over the entire wavelength range. Unlike calibration filters (e.g. holmium oxide), which must be calibrated themselves, the lamps' emission lines provide a primary reference standard, so they do not need to be recalibrated. For easy maintenance, all lamps and the flow cell are accessible from the front of the device. Specifications:. Type: Specifications Source: D2 lamp, Hg lamp for wavelength calibration.
