Dual-FL - The world's fastest Fluorometer
Overview
HORIBA Scientific combined the world’s only CCD based benchtop spectrofluorometer with a UV-VIS spectrophotometer and created the Dual-FL.
The Dual-FL features spectral rates as fast as 80,000 nm/s, and a water Raman S/N sensitivity greater than 20,000:1 RMS.
Collect incredibly rapid kinetics data, or complete excitation emission matrix (EEMs) in seconds.
And, it also has a built-in UV-VIS spectrophotometer. Use it as your lab UV-VIS, or collect simultaneous dual-mode fluorescence and absorbance data to correct inner-filter effects in your spectra.
