Description:

The 2475 pairs a 150 W pulsed-xenon lamp with dual holographic gratings, allowing independent selection of excitation (200–890 nm) and emission (210–900 nm) bands, each defined by 20 nm slit optics. Four simultaneous 2-D channels or a single 3-D spectral channel can be sampled at up to 20 Hz, making the detector ideal for gradient scouting and impurity profiling. Wavelength accuracy is factory-verified to ±3 nm with a patented erbium filter, and repeatability is ±0.25 nm—critical for regulated methods. The axially illuminated 13 µL stainless-steel flow cell tolerates 145 psi and swaps in seconds without tools. Sensitivity tops 1000:1 Raman S/N, letting analysts quantify pg-level fluorophores without pre-column concentration. A 20-pin rear header exposes four event inputs/outputs and analog voltages, while Ethernet, IEEE-488 and RS-232 ensure legacy system compatibility. Despite its power, the detector draws just 280 VA and fits the standard Waters 13.5 × 8.2 × 24 in chassis so it racks flush with Alliance™ or Arc™ modules.

Economic Advantage:

Because the 2475 can scan “on-the-fly” during a run, labs need only one detector to develop methods and execute production assays, eliminating the cost of a separate scanning fluorometer. Its maintenance-free xenon lamp (2000 h warranty) lasts four times longer than mercury lamps, slashing consumable spend.
