Tömeganalizátoroknak, often translated as mass spectrometers, are analytical instruments used to measure the mass-to-charge ratio of ions. This capability allows them to identify and quantify the different chemical components within a sample. The fundamental principle behind mass spectrometry involves ionizing a sample, separating the resulting ions based on their mass-to-charge ratio, and then detecting these separated ions.

The ionization process can be achieved through various methods, such as electron ionization (EI), electrospray ionization (ESI), or matrix-assisted laser desorption/ionization (MALDI), depending on the nature of the sample. Once ionized, the ions are accelerated into a mass analyzer, where magnetic or electric fields are used to separate them. Common types of mass analyzers include quadrupole, time-of-flight (TOF), and magnetic sector analyzers. The separated ions are then detected, and their abundance is recorded as a function of their mass-to-charge ratio, producing a mass spectrum.

Mass spectrometry is a versatile technique employed across numerous scientific disciplines. In chemistry, it is used for determining molecular weights, identifying unknown compounds, and analyzing reaction mechanisms. It plays a crucial role in pharmaceuticals for drug discovery and quality control, in environmental science for detecting pollutants, and in biology for protein identification and metabolomics. The sensitivity and specificity of mass spectrometers make them indispensable tools for research and analysis.
