The Double Beam UV-Vis Spectrophotometer LUV6HG is designed for high-precision optical analysis across a wide wavelength range of 190 to 900 nm. Equipped with a double beam optical system and a highly sensitive photomultiplier tube detector, it delivers excellent signal stability and accuracy, even at low light levels.
The system integrates three built-in light sources including deuterium, tungsten, and mercury lamps. The mercury lamp enables real-time wavelength calibration, significantly improving measurement reliability and long-term accuracy. The Czerny-Turner optical system ensures high resolution and minimal stray light, making it suitable for demanding analytical applications.
The instrument supports continuously adjustable spectral bandwidth from 0.1 nm to 5 nm, allowing flexibility for different analytical requirements, especially for samples with sharp absorption peaks. A large sample chamber accommodates standard 10 mm cells for both sample and reference measurements.
The system is controlled via PC software and supports advanced analytical functions such as photometric analysis, wavelength scanning, kinetic studies, and quantitative analysis. It complies with GLP/GMP requirements and includes features such as user management, audit trails, and data logging for regulated environments.
