★ Near-infrared qualitative and quantitative analysis software package, an external laptop is provided randomly, which can run Windows interface data acquisition, analysis and processing control software, perform single-channel spectral scanning, self-checking and calibration, in-machine modeling, inspection and transfer models, sample analysis, Multi-channel operation, channel scan curve storage/display comparison/printing report and other functions.
★ The tracing speed is less than 2min.
★ S400 is equipped with a PbS detector imported from Japan with cooling, and the reflectivity of the integrating sphere is over 95%. Built-in sample cell structure, two kinds of sample cells are used for different samples.
★ The background of the S400 rotary sample stage is fixed, and the sample can be rotated in all directions for multi-faceted measurement to solve the problem of uneven mixing.
★ The S410 is equipped with an Indium Gallium Arsenide detector imported from Japan. The sample cell with 4-connected cell structure is convenient for sample measurement.
The near-infrared spectral range is 800-2500nm. S400 belongs to diffuse reflection type, and its spectral range is 1300nm-2500nm; S410 belongs to transmission type, and its spectral range is 900nm-1700nm. The application of near-infrared analysis method in qualitative and quantitative analysis has the advantages of fast analysis speed, simple sample preparation and small amount, multiple analysis can be performed with a single spectrum, no sample consumption and no chemical pollution.
Near-infrared spectrophotometer can be widely used in the analysis and determination of grains, oil plants, food, animal feed, textiles, medicines, chemical products, etc. It is mainly used for rapid non-destructive qualitative and quantitative analysis of chemical and physical properties of liquid, non-suspended sol, solid, powder and granular, coating and other samples.
