Absorption Spectroscopy used to determine the Analytes by Qualitative and Quantitative based on excitation Wavelength, Example: UV/ViS spectrometer used with particular wavelength determines that analytes is present or not, if used linear calibration then concentration can be known.
Same applicable for all spectroscopy instruments uses source for excitation.
AAS is used to determine the concentration metalic elements in solution
first: for what purpose the absorption spectroscopy is used ?answer: absorpton spectroscopy or more we can call atomic absorption spectroscopie, and generally it is used to determine the concentration of an element in solution.
