Soft ionization mass spectrometry techniques: the motion laws of gaseous ions in weak electric fields

Ionization mass spectrometry technology has been studied for a relatively long time, and its theoretical development is relatively slow compared to chromatography and other fields. This article is based on the author's theory, establishes a corresponding model, introduces the equation for calculating the resistance coefficient of particles in the air, and explores the motion law of gas-phase ions in weak electric fields. Through the derivation of equations, mathematical equations were used to reveal the relationship between the measurable radius of the analyte and factors such as pressure, the relationship between the charge distribution of the analyte and its molecular weight, and the relationship between the measurable radius of the analyte and its collision cross-sectional area. Studying the motion law of gas-phase ions in weak electric fields can help to better understand soft ionization mass spectrometry technology, deepen the understanding of the basic principles of soft ionization mass spectrometry technology, and provide some reference for the development of soft ionization related ion sources
