Agilent 1290 Infinity G4212A DAD

This is a used Agilent 1290 Infinity G4212A Diode Array Detector, a key detection module for high resolution ultra performance liquid chromatography systems. The DAD offers fast scanning across a wide wavelength range, delivering the sensitivity and spectral resolution needed for accurate peak identification and purity assessment in pharmaceutical, biotech, and analytical chemistry labs. Its design supports the high pressures and low dispersion volumes required by UHPLC workflows, making it a natural fit for labs running the 1290 Infinity platform. The unit supports a broad range of applications including method development, quality control testing, and impurity profiling, where reliable UV-Vis spectral data is essential. Because it integrates directly into the Agilent 1290 Infinity ecosystem, it pairs readily with existing pumps, autosamplers, and column compartments already in service, minimizing requalification effort. Labs upgrading detection capability or expanding capacity on an existing UHPLC line will find this module a practical, cost effective addition. This detector has been in laboratory service and is sold in used condition. It has been pulled from an active analytical environment and is offered to labs seeking to expand or maintain their Agilent 1290 Infinity HPLC systems without the cost of new equipment. Buyers should plan on standard incoming qualification per their own SOPs prior to placing the unit into regulated use.
