The PTI QuantaMaster 8000 modular, research-grade spectrofluorometer has a signal-to-noise ratio of 30,000:1 rms for water Raman. It accommodates up to four excitation sources, six detection channels, and triple grating turrets for an extended wavelength range, and can be used with single or double monochromators for stray light rejection.
