Mass spectrometry

Definition

Mass spectrometry is an analytical technique used to measure the mass-to-charge ratio of ions, allowing for the identification and quantification of different substances within a sample. This method plays a crucial role in analyzing volcanic gases and geochemical components, providing insights into the composition and behavior of these emissions during volcanic activity.
