Atmospheric pressure ionization

Atmospheric pressure ionization is a technique used in mass spectrometry to analyze samples by converting molecules into ions at normal atmospheric conditions. This process involves applying energy, often through a hot gas or spray, to turn molecules in a sample into charged particles (ions). These ions are then guided into the mass spectrometer for identification and measurement. It allows direct analysis of complex, liquid, or gaseous samples without extensive preparation, making it a powerful tool for detecting and studying chemicals in various contexts such as pharmaceuticals, environmental testing, and clinical diagnostics.
