Analysis of Organic Compounds

Analysis of Organic Compounds

The main chemical components of living organisms are called organic compounds, which are molecules built around the element carbon (C). Organic compounds are present in a considerable number of fields. Therefore, sensitive analysis and detection of them is essential. Mass spectrometry (MS) is an analytical method that uses ionization and mass analysis of compounds to determine the mass, formula and structure of the compound being analyzed. It is capable of measuring multiple classes of organic compounds in a variety of biological specimens and artificial samples. According to the measured m/z and their peak intensities, the formula and chemical structure can be determined manually and / or by comparison with the reference spectral database [1].

Sensitive mass spectrometric analysis of organic compounds is important for various branches of chemistry and other fields, including physics, pharmacology, environmental science, biomedicine and materials science.

The Principle of Mass Spectrometry Analysis of Organic Compounds

MS is a powerful tool for the analysis of organic compounds, and its principle is described as follows.

In MS analysis of organic compounds, a sample is ionized, typically by electron ionization (EI) or electrospray ionization (ESI), which converts the sample into gas-phase ions. These ions are then separated by their m/z ratio using an analyzer such as a quadrupole, time-of-flight (TOF), or ion trap. The resulting mass spectrum provides information about the m/z ratio of the ions detected, and the relative abundance of each ion. This information can be used to determine the molecular weight, molecular formula and structural characteristics of the organic compound.
