Dual-FL具有极快的光谱扫描速度，获取EEMs的速度较其它仪器快百倍；Dual-FL系统灵敏度极高（水拉曼S/N：20,000:1，RMS方法）。由于同时获得吸收数据，自动校正高浓度样品的荧光内滤效应。Dual-FL具有无与伦比的扫描速度和简单易用的操作软件，帮助用户轻松完成样品测定工作。
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.
