Used WATERS Alliance 2795 XE #179648 for sale

WATERS Alliance 2795 XE is a type of state-of-the-art spectrometer that is used to measure the light intensity of spectral emission from a sample. It is employed to identify compounds in a complex mixture, differentiate between different types of samples, and monitor the changes in composition over time. This spectrometer features a vacuum ultraviolet (VUV) source, a Raman spectrometer, and an extended wavelength range which allows for a wider range of detection. The overall design of this device enables it to have exceptional sensitivity compared to other similar models. The source is a pulse-modulated deuterium-halogen lamp which has an output power of typically 100 mW. It uses a MagAOX optical filter which acts as a pre-filter to eliminate light emission that are outside of the useful wavelength range. A custom designed filter wheel supports a wide variety of interchangeable filters in order to facilitate optimal wavelength selection. The Raman spectrometer features a concave holographic grating with 2500 lines/mm and a spectrophotometer that are central for accurate recognition and classification of different compounds. It is also equipped with a pulse analyzer, which helps to reduce the thermal noise during operation. The wavelength range of this spectrometer is extended by a variable temperature accessory. This extends the range from 175 to 520 nm, enabling the device to detect a wider variety of components of a given sample. In addition, the device has an automated background correction feature that ensures accurate data analysis. Alliance 2795 XE is a powerful and versatile spectrometer that is capable of tackling various problems in analytical chemistry. Its source's high output power, Raman spectrometer's 2000 lines/mm grating, and extended wavelength range provides this device with the accuracy and sensitivity required to quickly and accurately identify and determine the composition of compounds in a sample.
