WebJul 16, 2024 · The key difference between atomic absorption spectroscopy and UV visible spectroscopy is that atomic absorption spectroscopy is based on the absorption of light by atoms or ions, whereas UV visible spectroscopy involves the absorption or reflectance of a part of the UV range and complete adjacent visible regions of the electromagnetic … WebSep 1, 2016 · UV detectors rely on the characteristics of many molecules to absorb energy when exposed to certain wavelengths of light. For some molecules, the wavelength of absorption may be quite specific (for example, anthracene has a strong absorbance at 251 nm). Some classes of molecules have a common absorbance region, such as proteins …
