High signal to noise ratio 130:1 (Raman peak of water)

High speed scanning rate 3,000nm/min

Main function: wavelength scanning, time scanning

Multi-optional accessories: Samples of solid reflectance attachment, Polarization attachment, filter and special photomultiplier

Functions

1.Wavelength scanning wavelength scanning function mainly includes two data modes: fluorescence intensity and luminous intensity. The excitation spectrum and fluorescence spectrum of samples can be obtained by fluorescence intensity data model, which is a common method.
2.Time scanning time scanning is to collect the fluorescence intensity curve of the tested sample with time within the specified time interval. It can be used to monitor the physicochemical changes of the sample, and the kinetic method can be carried out.
3.Photometric method uses wavelength method for quantification, up to 20 standard samples can be measured, polygonal standard curve can be drawn through each point of the standard concentration, the preparation of regression standard curve can use the first, second, third power curve or broken line, and the correlation coefficient R and R2 can be obtained at the same time.
4. Powerful spectrum processing function, two spectrums can be added, subtracted, multiplied and divided, and can also calculate the area of the spectrum; with spectrum correction and shutter control, etc.
