The beam splitter allows simultaneous reference beam correction, so peaks will not shift as the scan speed changes. As the Xenon lamp is very intense, the Cary 50 can use a beam splitter without the loss in energy causing excessive photometric noise.The Xenon lamp flashes only when acquiring a data point, unlike a diode array which exposes the sample to the whole wavelength range with each reading, causing degradation of photosensitive samples.The Cary 50 can measure samples up to 3 Abs so you won't have to dilute as often.With a data collection rate of an impressive 80 points per second you'll have all the information you need about your kinetics assay.That means you can scan the whole wavelength range of 190-1100 nm in less than 3 seconds. The maximum scan rate is 24,000 nm per minute.The innovative design of the Cary 50, which incorporates a Xenon flash lamp, enables it to offer many advantages over traditional UV-Vis spectrophotometers. The Varian Cary 50 Conc UV-Vis Spectrophotometer makes it possible for all users to experience the power of a Cary system.
