Instrument information

Brand : Shimadzu
Model : UV-1900i
Brief description:The UV-1900i is a double-beam UV-Vis Spectrophotometer using Shimadzu's original LO-RAY-LIGH™ diffraction grating technology. It boasts a high resolution of 1 nm, the lowest level of stray light and noise in its class, as well as an ultra-fast scan function allowing for data acquisition at 29,000 nm/min. It also features a multi-language interface that is easy to use while providing a diversity of measurement modes such as photometric, spectrum, quantitation, kinetics, time-course, and bio-methods. The UV-1900i is capable of high-accuracy quantitative analysis, detection of low-concentration components, and can perform analysis compliant with Pharmacopeia (JP, USP, and EP). The standard LabSolutions UV-Vis control software provides labor-saving measurements and allows for efficient analysis and integrated data management.
