It may be used to identify the elements and isotopes of a sample, to determine the masses of molecules, and as a tool to help identify chemical structures. In certain types of optical spectroscopy, the radiation originates from an external source and is modified by the system, whereas in other types, the radiation originates within the system itself. In simplest terms, spectroscopy requires an energy source (commonly a laser, but this could be an ion source or radiation source) and a device for measuring the change in the energy source after it has interacted with the sample (often a spectrophotometer or interferometer). Mass spectrometry is an analytic method that employs ionization and mass analysis of compounds to determine the mass, formula and structure of the compound being analyzed. Nature 293:270–5.

Spectroscopic analysis and mass spectrometry both provide valuable information on the chemical composition of DOM. 2013;525:371-93. doi: 10.1016/B978-0-12-397944-5.00018-3. The Mass Spectrometer In order to measure the characteristics of individual molecules, a mass spectrometer converts them to ions so that they can be moved about and manipulated by external electric and magnetic fields. A critical issue for mass spectrometry-based quantification is the need to have a set of authentic standards labelled with isotopes. Principle of Mass Spectrometry. Mass spectrometry is widely used in chemistry for elemental and molecular structural analysis. Mass spectrometry analysis alone or coupled to either gas chromatography (GC) or liquid chromatography (LC), with their characteristic high sensitivity and specificity, is becoming increasingly popular for determining lipid, protein, vitamin, and other trace elements. Recent advances in mass spectrometry (MS)-based proteomics have enabled tremendous progress in the understanding of cellular mechanisms, disease progression, and the relationship between genotype and phenotype. Based on Newton’s second law of motion and momentum, a mass spectrometer uses this property of matter to plot ions of varying masses on a mass spectrum.
