Pulse field enrichment ion migration tube

Abstract

The invention relates to a pulse field enrichment ion migration tube. The pulse field enrichment ion migration tube is characterized in that high-voltage pulse, which is synchronized to ion gate open pulse, is applied to a pulse electrode set between an ion source and an ion gate, the movement speed of ions is greatly improved during a period of opening the ion gate, and more ions are enabled to pass the ion gate; and meanwhile, spatial focusing is carried out on an ion cluster passed the ion gate by using the difference, which is caused by the high-voltage pulse, in electric field intensity at two sides of the ion gate, and the original resolution of the iron migration tube is maintained.

AI Technical Summary

Benefits of technology

This technology improves how well it works when analyzing molecules that move through an electric field compared with other methods like mass spectrometry or liquid chromatography. It allows us to measure very small quantities quickly while maintaining high accuracy.

Problems solved by technology

The technical problem addressed in this patents relates to improving the accuracy or sensitivity of detectors made up of multiple components such as an electron gate, which are commonly found in mass analysis instruments like IMS. While these devices work well at high temperatures but they may also suffer low detection efficiencies due to their use of electrons. To address this issue, there exist techniques called electronic nose technology, where specific parts of the device help identify charged particles more accurately while reducing noise levels.
