Electrospray Ionization Mass Spectrometry
Electrospray Ionization Mass Spectrometry (ESI-MS) is a powerful analytical technique used to identify and quantify small molecules and macromolecules. It functions by taking a sample and using an electric field to charge and ionize the sample molecules. These ions are then acted upon by a mass spectrometer, which can accurately measure the mass-to-charge ratio of the sample ions. By studying the mass-to-charge ratio, scientists can identify different molecule types and even determine the structure of a sample. ESI-MS is used in various industrial and scientific applications, such as food safety testing, drug analysis, environmental studies, and proteomics.
