Desktop grating spectroPhotoMeter

A desktop grating spectrophotometer disperses the light source into monochromatic light using a grating. The sample absorbs light at specific wavelengths, causing changes in the signal, and the detector measures transmittance or absorbance. It is used for determining solution concentrations and color analysis, as well as monitoring component content in the chemical and environmental protection fields.
Selection
When selecting, consider that the measurement wavelength range should cover the characteristic bands of the sample, and the spectral bandwidth should match the detection accuracy requirements. Pay attention to baseline stability and stray light indicators. Configure cuvettes or integrating sphere attachments based on the sample's morphology, and verify the instrument's calibration functions and the suitability of its operating interface.
