A UV-Vis spectrophotometer is an analytical instrument that measures the amount of ultraviolet (UV) and visible light that is absorbed by a sample. It is a widely used technique in chemistry, biochemistry, and other fields, to identify and quantify compounds in a variety of samples.
There are some common types of spectrophotometers include: UV-vis spectrophotometer: Measures light absorption in UV and visible ranges (200-800 nm). Used for quantification of many inorganic and organic compounds. 1. Infrared spectrophotometer: Measures infrared light absorption, allowing identification of chemical bonds and functional groups. 2.
The vast majority of liquid chromatographic systems are equipped with ultraviolet (UV) absorption detectors. The most common UV-Vis detectors used are variable wavelength detectors (VWD), photo diode array detectors (PDA), and diode array detectors (DAD). [4] Variable wavelength detectors decide in advance which wavelength is needed for the ...
A vendor-independent software for processing chromatography (LC, GC, SFC) data with any combination of detectors, e.g. LC-MS-UV-VIS, GC-MS, SFC-MS-UV in one environment. This multiplatform and web-based software was created by Mestrelab Research, S.L. matchms Open source
Using the Bausch & Lomb Spectronic 20 Colorimeter, 1962. The Spectronic 20 is a brand of single-beam spectrophotometer, designed to operate in the visible spectrum [1] across a wavelength range of 340 nm to 950 nm, with a spectral bandpass of 20 nm.
