Abstract

Mass spectrometry is the most effective method for determining molecular structure. It typically offers information on a substance's molecular weight, but it may also show atomic mass units and up to ten-hundredths of atomic mass units depending on the mass analyzer's accuracy. Furthermore, it offers information on the ions (positive charged) created in between the ionization process, related to the molecule's chemical structure and the type of bonds. During these years, the technique paired with the use of software and databases, has been spectacular, enhancing ionization processes and ion analysis. This chapter will demonstrate how mass spectrometry has aided in quality control analysis.
