Sähkösumutusionisaatio

Sähkösumutusionisaatio is a Finnish term that translates to electro-atomization ionization. It refers to a process where a liquid is dispersed into extremely fine droplets through an electric field, leading to ionization. This technique is often employed in analytical chemistry and mass spectrometry for sample introduction.

The core principle involves applying a high voltage to a liquid sample as it flows through a fine needle or nozzle. This electrical charge causes the liquid to break apart into tiny, charged aerosol particles. As these droplets evaporate, the analyte molecules within them become further ionized. The resulting ions are then directed into a mass spectrometer for analysis, allowing for the identification and quantification of specific substances.

Sähkösumutusionisaatio is known for its ability to generate stable ion beams and its compatibility with a wide range of liquid matrices. Its efficiency in producing ions at atmospheric pressure makes it a convenient and widely used ionization method. The technique is particularly valuable for analyzing complex biological samples, environmental pollutants, and pharmaceutical compounds. Variations of this method exist, but the fundamental concept of using electric fields to create charged aerosols for ionization remains consistent.
