Agilent 1260 Infinity II HPLC MWD Detector (G7165A) (New)

The Agilent 1260 Infinity II Multiple Wavelength Detector (MWD) is an advanced liquid chromatography (LC) detector designed for high-performance multi-wavelength analysis. Engineered for superior sensitivity, selectivity, and operational efficiency, this detector enables simultaneous detection of up to eight compound-specific wavelengths within a broad 190–950 nm range.

Built with Agilent’s state-of-the-art diode array technology, the detector delivers ultra-low noise levels (< ±7 μAU), ensuring accurate quantification of trace-level compounds. With a high-speed 120 Hz data acquisition rate, it supports fast LC applications while maintaining high resolution. The electronic temperature control (ETC) stabilizes baseline performance under fluctuating environmental conditions, optimizing both sensitivity and linearity.

Ideal for analytical laboratories, the 1260 Infinity II MWD ensures high data integrity through radio frequency identification (RFID) tracking of flow cells and UV lamps, automatic wavelength verification, and compliance with Good Laboratory Practice (GLP) requirements.
