D1100+ UV-Vis Detector

The D1100+ UV-Visible Detector features an optimized optical path heat dissipation structure that maintains stable temperature, significantly reducing baseline noise and drift for long-term reliability. It supports automatic spectrum scanning, enabling full-wavelength UV-Vis absorption scans under static mobile phase conditions to quickly determine the optimal detection wavelength. The wavelength-time program allows automatic wavelength switching at preset times during a single analysis, ensuring multiple components are detected at their best wavelengths and greatly improving sensitivity. A convenient side-mounted solvent flow outlet simplifies waste solvent discharge. These features make the D1100+ a high-performance, user-friendly detector for HPLC systems.
