OPTIONAL: Waters 474 performance maintenance kit (p/n WAT052665). Waters 474 Scanning Fluorescence Detector brings a new, higher level of sensitivity to HPLC fluorescence detection. When Waters introduced the 470 Scanning Fluorescence Detector, quantitation of naturally fluorescing and derivatized compounds was achieved at levels lower than previously possible by HPLC. That high sensitivity has been surpassed by the Waters 474 Scanning Fluorescence Detector.

Waters 474 Detector optimizes the utility of fluorescence detection with advanced programming and scanning capabilities. Up to 10 programmed methods of 64 program steps each can be stored and automatically executed to change excitation and/or emission wavelengths, detector output gain, or attenuation. This allows optimum detection of multiple analytes in a single run. Excitation and emission spectra can be scanned in a stopped flow mode or on the fly, and the data reviewed post run. The 474 Detector will store up to 10 excitation and emission spectra. The improved electronics in the optics bench minimize baseline noise, which improves sensitivity. For maximum sensitivity, the 474 Detector comes standard with a 16uL flow cell. Please contact us for complete used and refurbished Waters HPLC system, warranty and service contract details.
