The Duetta two-in-one system from Horiba Scientific eliminates the need for multiple scanning instruments. In addition to traditional fluorescence and absorbance spectroscopy modalities, the system features simultaneous Absorbance-Transmittance Fluorescence Excitation Emission Matrices (A-TEEM), providing better molecular fingerprinting and extended dynamic range due to automatic inner filter effect corrections. With an effective scan speed of 510,000 nm/min, Duetta can acquire an entire three-dimensional excitation emission matrix (EEM) in less than a second, significantly faster than a scanning, PMT-based, benchtop spectrofluorometer. With a standard fluorescence emission wavelength range of 250–1100 nm, the system also offers extended NIR fluorescence detection well beyond that of conventional PMT-based fluorometers.
