Title:
WIRE ELECTRODE ION CONTROL DEVICE STRETCHER AND WIRE TENSION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/056395
Kind Code:
A1
Abstract:
Disclosed are a wire electrode ion control device stretcher and a wire tension control method, which are used for ion generation, transport and mass analysis devices. The present invention can directly generate ions in an ion trap, and use wire electrodes arranged in a space to capture and trap the generated ions, and the ions are directly transported at an extremely low loss to a mass analyzer to obtain mass spectra of different mass ions. By means of the stretcher adjusting the tension of the wire and by means of measuring the sound frequency of the shifted wire so that the tension of the wire is kept consistent, the optimization of forming an ion trap electric field is ensured. Therefore, the present invention has a small and compact structure, has a detection means that is flexible and easy to operate, and is suitable for the fabrication and detection of a wire electron ion trap.
