Mass spectrometry is a method of detecting the amount of ions contained in a substance by converting it into 

gaseous ions and measuring the mass number and ion number. Substances are identified by analyzing the types 

and amounts of ions they contain.

The liquid or gaseous sample is vaporized and ionized by the ion source. When ionized molecules pass through 

the magnetic or electric field of the mass spectrometer, they are separated and analyzed due to the difference in 

mass charge.

Mass spectrometers are divided into several types according to the method of ionizing the substance and the 

structure of the part that analyzes the ion. Ionization can be done by running an electric current through the 

filament to create thermionic ions and causing them to collide with matter, or by applying a high voltage to exploit 

the tunneling effect.

In the analysis part, the method of selecting the ions to reach the detector through the action of electric or 

magnetic field and the method of accelerating the time of the ions to reach the detector are used for analysis. 

Wisman has a lineup of high-voltage power supplies for ionization, electric fields and detectors, DC high-power 

supplies for magnets that generate magnetic fields, and bipolar power supplies.

Wisman has a range of power sources that can be used for mass spectrometry.
