YL9120 UV/Vis Detector
Chapter 1. Introduction
The YL9120 UV/Vis Detector is the most sensitive and versatile absorbance detector available for HPLC.
It features dual wavelength capability, improved signal-to-noise performance, minimized drift and reduced
optical bandwidth. The YL9120 UV/Vis Detector is designed to provide higher performance in UV/VIS
detection for HPLC application such as development, analytical research and QA/QC.
