Maspektromeetria

Maspektromeetria is an analytical technique used to measure the mass-to-charge ratio of ions. It is employed to determine the elemental composition of a sample, identify unknown compounds, and quantify the abundance of known compounds. The process typically involves ionizing a sample, separating the ions based on their mass-to-charge ratio, and then detecting the abundance of each ion.

There are several ionization methods, including electron ionization, chemical ionization, and electrospray ionization, each suited for different types of samples and analytes. The separated ions are then analyzed using a mass analyzer, such as a quadrupole, time-of-flight, or ion trap. The detector then measures the intensity of ions at each mass-to-charge ratio, producing a mass spectrum. This spectrum is a plot of ion abundance versus mass-to-charge ratio, which serves as a unique fingerprint for the analyzed substance.

Maspektromeetria has broad applications across various fields. In chemistry, it is used for structure elucidation and reaction monitoring. In biology and medicine, it aids in proteomics, drug discovery, and disease diagnostics. Environmental science utilizes it for pollutant analysis, while forensic science employs it for identifying trace evidence. The sensitivity and specificity of maspektromeetria make it an indispensable tool for scientific research and industrial analysis.
