What is the difference between mass spectroscopy and mass spectrometry?

Posted May 24, 2022


Answer

Mass spectroscopy and mass spectrometry are distinctively different from each other. Spectroscopy is simply the theoretical method to science, there are no results in the outcome of the experiment. Spectroscopy studies the absorbance and emittance of light and radiation by matter. Different types of spectroscopy include astronomical spectroscopy, biomedical spectroscopy, absorption spectroscopy, and energy dispersive x-ray spectroscopy.  Spectrometry is used for gaining a quantitative measurement of the absorbance and emittance of light; and unlike spectroscopy, there are results in the outcome of the experiment. For example, it can quantify the molecular mass, optical density, or transmittance of a compound.
