How does a uv spectrophotometer work
WebMay 21, 2024 · UV-Vis spectroscopy is an analysis method that compares the number of distinct wavelengths of UV or visible light absorbed or reflected by a sample to a standard or null sample. Because this spectroscopic approach is based on the usage of light, we need first to look at the characteristics of light. WebSpectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer measures the spectrum of the masses of ...
