Heraeus Noblelight GmbH’s D2plus deuterium lamps are a next-generation concept that instrument manufacturers can design into their systems for higher throughput and precision analytical results. A new design and proprietary enhanced lifetime performance (ELP) technology combine to produce high stability and low optical noise. OEM customers benefit from the company’s experience with UV/quartz glass and coatings, and metals and ceramics. Deuterium lamps are now available with 0.5- and 1-mm apertures and offer a minimum lifetime of 2000 h for UV-VIS spectrophotometers, and for high-performance and ultrahigh-performance liquid chromatography instruments. The ELP technology ensures 50% more initial intensity and greater than two times the residual intensity compared with conventional deuterium lamps, according to the company.
