UV-1900i | UV-VIS Spectrophotometer


UV-1900i | UV-VIS Spectrophotometer

The Shimadzu UV-1900i 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.


UV-1900i overview

Easy to Operate, Obtain Answers Easily and Rapidly
  • Ergonomic Hardware Design: The control panel is ergonomically designed and positioned at the optimum viewing angle for the user. Users can operate easily with any posture. Since the panel is pressure-sensitive, the device can be operated with gloved fingers or a stylus pen. The stylus pen can be stored right next to the control panel.
  • Easy-to-Use Interface Grasp the Current Status and Operating Procedures at a Glance: The UV-1900i on-screen user interface includes large, easy-to-see icons deployed on a black background, so the instrument settings are evident at a glance. In addition, the large, easy-to-see icons improve intuitive understanding, which enables users to quickly become familiar with the operations. Furthermore, the user interface is designed to minimize transitions between windows, so users do not get confused during the operations.
  • Navigation Tabs Improve Usability: In quantitation mode on the UV-1900i, the stages of the entire measurement process and the current status are always shown on the display. As a result, users know immediately what to do in the next step.
High Performance to Meet Diverse Needs
  • Low Stray Light: Stray light is at 0.5 % max. (198 nm), making accurate measurements are possible up to the vicinity of 2 Abs even in the ultraviolet region. In addition, high-concentration samples can be quantified accurately.
  • High Reproducibility and Repeatability Accuracy:The figure on the right is a calibration curve for caffeine, created with absorbance at 273 nm. The calibration curve has an Abs = 0.0528 Conc. The lower limit of quantitation determined from the standard deviation is 0.0051 mg/L.
Full Support for Pharmacopeia, GLP/GMP, FDA 21 CFR Part 11 and Other Regulations
  • Instrument Validation Functions Compliant with JP, USP, and EP: This instrument can not only run checks for nine JIS items, but also those stipulated in the Japanese Pharmacopoeia (JP), United States Pharmacopeia (USP), and the European Pharmacopoeia (EP). Naturally, the hardware is also compliant with the specifications required by each Pharmacopeia. In addition, the check conditions can be saved. As a result, once the conditions are saved, checks can be performed easily just by calling them up as needed. Check results can also be saved.
  • Improved Security Functions: An external control security function has been added to provide more support for compliance with regulations. Three user authority levels, “Administrator”, “Developer”, and “Operator”, can be set for instrument users.
  • Resolution of 1 nm, the Highest in its Class: In addition to achieving a resolution of 1 nm, the highest in its class, by using a monochromator with a Czerny-Turner mounting, the UV-1900i also features a compact, bright optical system. The instrument is more than capable of meeting the wavelength resolution required in the European Pharmacopoeia.
