Agilent 1200 Series G4212A DAD SL

This used Agilent 1200 Series G4212A DAD SL is a diode array detector module engineered to provide full spectral UV-Vis detection for compounds separated on an Agilent 1200 Series HPLC system. It captures absorbance data across a wide wavelength range simultaneously, allowing analysts to identify and quantify multiple compounds within a single chromatographic run based on their unique spectral signatures. This detector has been tested and is offered in good working condition, ready for installation into a compatible LC stack. The diode array design gives laboratories powerful peak purity and identification capabilities beyond what single wavelength detectors can offer, which is particularly valuable in method development, impurity profiling, and forensic or pharmaceutical analysis where compound confirmation matters. Its SL footprint matches the compact 1200 Series module family, so it drops into existing systems built around Agilent pumps, autosamplers, and column compartments without requiring a redesign of the bench setup. Analysts gain flexible wavelength selection and spectral overlay tools that support both routine quantitation and more investigative analytical work. Sourcing this DAD SL detector used gives laboratories a cost effective way to add or restore diode array detection to an existing 1200 Series system, or to keep a backup unit on hand for uninterrupted operation. It is well suited to pharmaceutical, chemical, environmental, and academic research settings that depend on dependable spectral detection.
