This used Waters 474 Fluorescence 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.
The instrument was tested in our laboratory and is in a good state. Currently we have 2 systems on stock.
