Used DIONEX / THERMO AS-50 #9274608 for sale

DIONEX / THERMO AS-50 is a diode array spectrometer and analytical instrument that operates in the ultraviolet/visible spectral region. This spectrometer is designed to measure the emission, absorption, and transmission spectra of electrical and optical materials, as well as to visualize spectral information. With its broad wavelength range, DIONEX AS-50 can measure samples from 200-900 nm with maximum resolution at the visible/near-ultraviolet range (250-400 nm). THERMO AS-50 utilizes differential absorbance spectroscopy (DAS) technology to measure the components of samples in both liquid and solid phase samples. During the analysis, the sample is placed in a cuvette and passed through a wavelength-stabilized diode array. Simultaneously, a reference beam is generated with the help of a ceramic hollow cathode lamp. The spectrometer measures the absorbance of a sample, subtracting the reference absorbance, and determines the peaks present in the sample. The overall set-up of AS-50 is relatively compact, measuring 12.8 "x 7.5" x 6" (32.4 cm x 19 cm x 15 cm). It includes a 10-inch thin-film-transistor (TFT) display, a user-friendly interface, and a storage system. The spectrometer also features a wide range of operational modes, such as the single-scan mode, the kinetic mode, the quad-scan mode, and the sequential scan mode. The software lets users set parameters for their experiment, and the data collected from the spectrometer can be exported in a variety of formats such as text files, JPEGs, and vector files. DIONEX / THERMO AS-50 is ideal for characterizing and quantifying materials via transmission, reflection, and absorbance spectroscopy. Its low noise diode-array design allows superb wavelength resolution, excellent linearity, and fast response times. The spectrometer's low-noise electronics make it suitable for measurements in industrial, medical, and pharmaceutical applications. Furthermore, DIONEX AS-50 has been designed to be compliant with the FDA's 21 CFR Part 11 regulations, allowing it to be used in regulated environments where full traceability is essential.
