Method for trapping gas molecules can also use ionizing adsorption. Using a high-speed electron impact gas molecules can be obtained positive ion, positive ion in the electric field was banished to the negative electrode,titanium ingot price and after due to intermolecular Vander Vauls Ley was metal adsorption and no longer leave electrode.
This reduces the space gas molecule concentration can be obtained, the purpose of vacuum. This phenomenon is called electric clearance, using the electric clearance to reach the purpose of degassing pump ( titanium pumps )called ion pump. Gas ion pump on the adsorption of no selective.
