In astronomy research, an UV / Vis spectrophotometer helps the scientists to analyze the galaxies, neutron stars, and other celestial objects Advantages of Spectroscopy (a) Spectroscopic methods are much more rapid and much less time consuming. Atomic absorption spectroscopy (AAS), in both flame and electrothermal modes, is one of the best methods for determination of the metal concentrations in various specimens that dissolved in acid (Kalbasi and Mosaddegh, 2012).Separation, preconcentration, and dissolution of samples are the vital steps in . Therefore, it can be used for various purposes like UV - Visible, Infrared, Raman, Atomic Absorption Spectroscopy, etc. In both of these disciplines, scientists employ special equipment to help them analyze or "see" things that the human eye could not detect on its own. In absorption spectroscopy a photon is absorbed by an atom or mol- It occurs in the same wavelength range, but results from an excited state emitting a photon of a lower energy than it absorbed. However, preparing to use one takes a lot of time and effort because outside light or small vibrations can interfere with the readings. Color detection is the primary use of a spectrophotometer where it takes a reference and provides the percentage of transmittance or reflectance from an object Well, NMR spectroscopy is a non-sporting method of analysis. For the sake of accuracy in quantitation, it is of interest to compare these methodologies and determine if good correlation can be achieved between the DOI: 10.1016/J.ACA.2003.08.048 Corpus ID: 32337924.

You have to start with a good scientific question: for example, why does UV . can be established unequivocally, and where kinetic processes can sometimes be interrogated. For about 130 years, the Bouguer-Lambert-Beer law has been used as the quantitative basis of absorption spectroscopy. Atomic Absorption Spectrometry (AAS) is an analytical technique that measures the concentration of an element by measuring the amount of light (intensity of light) that is absorbed - at a characteristic wavelength - when it passes through a cloud of atoms of this element. The most common type of light detector in UV/Vis spectrophotometers is the photomultiplier tube (PMT). (2020, May 18). For instance, hydrocarbons can be detected through infrared spectroscopy. On the other had, UV and IR spectroscopies, and Raman spectroscopy, require a lot more.
