EDISON, N.J., Sept. 6, 2012 — The benchtop Dual-FL manufactured by Horiba Scientific combines a CCD-based spectrofluorometer and a spectrophotometer for simultaneous rapid collection of fluorescence and absorbance data. It addresses the need for speed when collecting spectral data and complete excitation-emission matrices (EEMs). Dual-FL features spectral rates as fast as 80,000 nm/s and acquires EEMs up to 100 times faster than other instruments, according to the company. With its sensitive cooled back-illuminated CCD detector for rapid collection of emission spectra, and an excitation double monochromator for good stray light rejection, the device offers a signal-to-noise ratio >20,000:1 rms. The simultaneous absorbance data can be used to correct inner-filter effects in measurement of high-concentration samples, eliminating the need for time-consuming dilutions.
