Main Features
Rich functionality - meets various customer analytical needs:
The hardware is equipped with VP function to record service history and operational records, which complies with GLP/GMP requirements. The system controller is additionally equipped with a built-in clock, thermometer, hygrometer and other ergonomic functions.
High performance - meets the most stringent requirements for instrumentation:
The detector uses an imported deuterium lamp, a photodiode and a concave diffraction grating with a frequency of 1200 lines/mm, forming a dual-beam monochromator. Adopts precision-machined double-lens flow cells, high-precision wavelength control microprocessor, and dual-channel high-speed sampling to achieve low noise, low drift, and ultra-high sensitivity.
The VI2010 workstation meets the requirements of various regulations.
Reliable results – provide the accuracy required by the customer:
In comparative tests with imported devices, the analysis results demonstrate a high degree of convergence.
Easy to use - makes the software easier to learn:
The software is designed in multi-circuit mode and is easy to use.
Elegant design - meets aesthetic requirements:
The appearance of the device is distinguished by its elegance and visual appeal.

Software
A dedicated HPLC chromatography workstation is integrated directly into the detector. There are three software options - VI2010, N2000 and N3000 - available for customers to choose from, to suit different user requirements.
VI2010 L2 is software for the VI2010 chromatography workstation, designed for use in conjunction with liquid chromatographs and featuring reverse control functionality. It includes features such as user account management, password policies, access rights configuration, electronic signature, audit and traceability, equipment monitoring, system compatibility assessment, component verification and timing programs, and is compliant with GLP/GMP, FDA, 21CFR Part II, CTD chemical registration requirements, and regulatory requirements for chromatography data workstations used in drug registration research and management chromatographic data.
