tömegspektrófiás

Tömegspektrográfia is a scientific technique used to measure the mass-to-charge ratio of ions. This is achieved by ionizing molecules and then separating these ions based on their mass-to-charge ratio. The separated ions are then detected, and the resulting data provides a spectrum representing the abundance of each ion at its specific mass-to-charge value.

The process typically involves an ionization source, a mass analyzer, and a detector. Various ionization methods exist, such as electron ionization, chemical ionization, or electrospray ionization, chosen based on the sample type and desired information. The mass analyzer, which can be magnetic, electric, or time-of-flight based, separates the ions. Finally, the detector records the number of ions arriving at different mass-to-charge ratios.

Tömegspektrográfia is a powerful analytical tool with wide-ranging applications in chemistry, biology, physics, and medicine. It is used for identifying unknown compounds, determining the elemental composition of a sample, quantifying the amount of a substance, and studying the structure of molecules. Its high sensitivity and specificity make it invaluable in fields like pharmaceutical analysis, environmental monitoring, and forensic science.
