Agilent Infinity II G7115A DAD WR Diode Array Detector Overview
Agilent Infinity II G7115A DAD WR Diode Array Detector is a wide‑range UV‑Vis detector designed for Agilent 1260 Infinity II HPLC systems, providing full‑spectral and multi‑wavelength detection for analytical applications. It operates across a 190–950 nm wavelength range using a dual deuterium and tungsten lamp design and a 1024‑element photodiode array for accurate spectral acquisition.
With data acquisition rates up to 120 Hz, the G7115A DAD WR supports fast LC and UHPLC separations, enabling reliable peak detection, spectral analysis, and peak purity assessment. The detector allows simultaneous monitoring of up to eight wavelengths, programmable slit widths, and compatibility with a wide range of RFID‑enabled flow cells. It integrates seamlessly with Agilent OpenLab and ChemStation software, making it a versatile UV‑Vis detection solution for modern chromatography workflows. The Agilent Infinity II G7115A DAD WR Diode Array Detector is commonly used in pharmaceutical, environmental, and analytical laboratories requiring reliable UV‑Vis detection.
