1000-0999, Agilent Quartz Window for FLD (fluorescence) detectors

The Agilent Quartz Window is an optical replacement component for compatible liquid chromatography fluorescence detectors. In fluorescence detection, stable transmission through the optical pathway is essential for reliable excitation and emission measurements. Quartz optics provide appropriate optical transmission for fluorescence instrumentation, while clean, correctly seated window surfaces help limit scattered light and optical background. This replacement window supports service and restoration of compatible Agilent fluorescence detector modules, including the G1321A, G1321B, G1321C, G7121A and G7121B models. Inspect the optical assembly and follow the detector service procedure when a window has become contaminated, scratched or damaged. Handle the window by its edges and use optics-compatible cleaning practices to prevent residues and fingerprints from entering the light path. After replacement, perform the relevant detector checks and verify baseline stability and fluorescence response with suitable standards. This item is an optical repair part rather than a complete fluorescence detector, lamp or flow cell, and mechanical fit should be verified against the instrument model.
