Horiba Scientific has introduced a new fluorescence/UV-vis spectrometer that has been designed to address a new market for Horiba, the so-called mid-market, with a lower price point analytical fluorometer. The Duetta™ two-in-one system eliminates the need for multiple scanning instruments. In addition to traditional fluorescence and absorbance spectroscopy modalities, the new 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–1, Duetta can acquire an entire three-dimensional excitation emission matrix (EEM) in less than a second. With a standard fluorescence emission wavelength range of 250–1100 nm, Duetta also offers extended NIR fluorescence detection well beyond that of conventional PMT-based fluorometers. Duetta features EzSpec, a new software interface from Horiba Scientific which has touchscreen utility, simplified use and a selection of Apps for routine analysis.
