Spectral Analyzer

A spectrophotometer decomposes composite light into monochromatic light through a prism or grating, measuring the degree of absorption or reflection of light by a sample at different wavelengths. It is used to detect material composition, analyze colors, and determine substance content and color differences in chemical engineering and food testing.
Selection
When selecting a spectrometer, it is important to consider whether the measurement wavelength range covers the characteristic bands of the sample, whether the accuracy meets the detection standard requirements, whether the sample adapter is compatible with solid and liquid forms, and whether the equipment's stability and ease of operation are suitable for daily use environments.
