Page 4: Spectrophotometer Overview
C-7000 Series User Manual PEAK INSTRUMENTS INC. I. Spectrophotometer Overview 1. Basic Operating Principle 1) The nature of absorption: spectrophotometric analysis method is the use of substances to choose a different wavelength of light absorption characteristics established. Typically using a prism or grating to obtain monochromatic light that passes through the continuous monochromatic solution, the solution was measured and the absorption of each wavelength, the absorption spectrum curve obtained. - Page 5 C-7000 Series User Manual PEAK INSTRUMENTS INC. monochromatic, at low concentrations, curve remains linear, but larger concentrations, with concentration increases, AC curve bend more serious, there is Beer's law applies only to dilute solutions F. Stray light, stray light entering the detector means is unnecessary components to be tested at other wavelengths outside the range of the wavelength spectral bandwidth.
