UV-1900i Plus | UV-VIS Spectrophotometer

The Shimadzu UV-1900i Plus is a UV-Vis spectrophotometer for routine and regulated analysis. It delivers a wavelength resolution of 1 nm. This is among the highest in its class. The optical system provides very low stray light. Noise levels are also kept to a minimum. This supports accurate results across a wide concentration range. The system supports fast scanning up to 29,000 nm per minute. This improves throughput in busy laboratories.

The UV-1900i Plus includes a clear multi-language user interface. It is easy to operate with minimal training. The system supports multiple measurement modes. These include photometric, spectrum and quantitation modes. Kinetics, time-course and bio-methods are also supported. The instrument delivers reliable quantitative analysis. It supports detection of low-concentration components. It is suitable for use under JP, USP and EP requirements. LabSolutions UV-Vis software is supplied as standard. This supports efficient measurements and integrated data handling.

UV-1900i Plus Overview

Easy operation and fast answers

The UV-1900i Plus is designed for simple operation. The control panel is positioned at a comfortable viewing angle. Users can operate the system from any posture. The screen responds to gloved hands. A stylus can also be used. The stylus is stored beside the control panel for convenience.

Clear interface and guided operation

The on-screen display uses large icons. The background is dark for contrast. Instrument status is visible at a glance. This helps users understand settings quickly. Screen transitions are kept to a minimum. This reduces confusion during operation. In quantitation mode, navigation tabs show each step. The current stage is always visible.

Performance for demanding applications

Low stray light

Stray light is limited to a maximum of 0.5 percent at 198 nm. Accurate measurement is possible close to 2 Abs. This applies in the ultraviolet region. High-concentration samples can also be measured reliably.

High reproducibility

The UV-1900i Plus delivers consistent results. This supports reliable calibration curves. It also supports low limits of quantitation. This is important for trace analysis.

Compliance and security support

Pharmacopeia-aligned validation

The UV-1900i Plus supports validation checks for JP, USP and EP. JIS checks are also supported. Validation conditions can be stored. They can be recalled when required. Results can be saved for records and review.

User access control

Security functions support regulated environments. User access levels can be defined. These include Administrator, Developer and Operator roles. External control security is also supported.

Optical system

The UV-1900i Plus uses a Czerny–Turner monochromator. This enables true 1 nm resolution. The optical system is compact and efficient. It meets European Pharmacopoeia wavelength requirements. This supports confidence in regulated analysis.
