High sensitivity: based on high-efficiency optical design and weak signal detection technology, the water Raman peak signal-to-noise ratio can be greater than 200 (P – P) to the leading domestic and international advanced level.
High scanning speed: the high-speed digital signal processing unit provides the world’s fastest scanning speed at 48000nm/min. Only 1 second to get classic fluorescence spectra, and 1 minute to get high-quality three-dimensional fluorescence spectra.
Wide Spectral measurement range: using a double monochromator design, excitation and emission wavelength range covering 200 nm to 900 nm, meet the needs of most fluorescence analysis.
Excitation light path monitoring system: the instrument is equipped with an excitation light dual beam ratio monitoring system to ensure the fluorescence signal is high and stable.
High-quality assurance: using Hamamatsu’s high-quality Xenon light source and photoelectric multiplier tube detectors and instruments to provide sufficient light intensity signal and detection sensitivity.
Built-in optical gate: Built-in optical gate, designed for unstable samples.
