Fonctionnement

Ratio double-beam dispersive UV-Vis: imported flange-mounted high-energy D2 lamp + tungsten lamp source dispersed by a high-performance blazed holographic grating (low stray light ≤0.03 %) produces a stable monochromatic beam. The beam is split into sample and reference paths; the ratio is computed by the microprocessor, eliminating source-intensity drift and providing high measurement stability approaching high-end instruments. Fully automatic operations include auto 0 %T/100 %T/0 A, 8-cell cuvette changer auto-link, and micro-step mirror switching for rapid source changes without optical realignment.
