Dispersion SpectroMeter

A spectrometer decomposes composite light into monochromatic light using a prism or grating, measuring the absorption or reflection intensity of substances at different wavelengths. It is used to detect paint color formulations, ink colorfastness, plastic light transmittance, and to control color consistency in printing.
Selection
When selecting, consider that the wavelength range should cover the characteristic bands of the analyte, and the resolution should meet the requirements for spectral detail. Pay attention to the detector's sensitivity and signal-to-noise ratio, and ensure that the sample chamber size is compatible with the objects to be tested. Verify the instrument's calibration methods and maintenance cycles, and ensure that the software supports industry-standard analytical methods.
