elektroniionisaatio
Elektroniionisaatio, also known as electron ionization or EI, is a common method of ionization used in mass spectrometry. In this process, a sample is bombarded by a beam of energetic electrons. These electrons strike the atoms or molecules of the sample, knocking out one or more electrons from them. This results in the formation of positively charged ions, often referred to as molecular ions.
The energy of the electrons used in EI is typically around 70 electron volts (eV). This energy
The ions produced by EI are then separated and detected based on their mass-to-charge ratio. The resulting
EI is a relatively straightforward and inexpensive ionization technique, making it widely used in many analytical
