External spectroPhotoMeter

The external spectrophotometer uses a spectroscopic system to separate the light source into monochromatic light. The sample absorbs light of specific wavelengths, causing changes in signal, and the detector measures the intensity of transmitted or reflected light. It is used for determining solution concentrations, qualitative analysis of substances, and quantifying component contents in environmental monitoring and food inspection.
Selection
Select the measurement mode according to the sample type: transmission mode for liquids and reflection mode for solids. The wavelength range should cover the characteristic bands of the analyte, taking into account the instrument's resolution and stability. The sample chamber size should accommodate standard containers, and the detector sensitivity should match the expected signal intensity.
