FL-4000 Fluorescence Spectrophotometer is a high-quality analytical instrument and widely used for qualitative and quantitative analysis in various fields such as chemistry, pharmaceutical testing, materials, environmental protection, water quality, petrochemical industry, medical and health, food and nutrition etc.
– High speed scanning at 30000nm/min and high sensitivity with S/N ratio better than 150 (peak to peak)
– Wavelength Scan supports measurement of fluorescence, luminescence and phosphorescence at excitation, emission and synchronous modes, repeat scanning up to 20 times
– Time Scan supports measurement of fluorescence, luminescence and phosphorescence at specified Ex and EM wavelengths, and scanning period
– Photometry function supports quantitative measurement with different calibration curves and multiple wavelengths
– 3-D Scan supports measurement of fluorescence and phosphorescence at specified EX/EM spectral range and sampling interval, can be displayed on both 3-D and 2-D contour view
– Powerful spectrum processing such as peak searching, smoothing, derivative and arithmetic operation and area calculation
– USB interface, user friendly and powerful software functions
