Ion detection analysis is the promising tool for the fast detecting and control of trace organic compounds in the fields such as environmental research, national security, medical applications and food control. However, it is limited in analyzing the more trace compounds for its low sensitivity. Therefore, in this project we plan to research on the performance of the new DC-RF focusing field electrode structure in the ion detection instruments: Based on the ion detection instrument, the ion trajectories in that new electrode structure were simulated with the latest ion collision algorithm. And it was used to study performance improvement of the ion detection instruments.The anticipated achievement of this project is to develop a new ion collision model consistent with the actual situation and an accurate method to simulate ion motion trajectory in the electric field. At the same time, it has huge potential and great reference in improving the sensitivity of ion detection analysis with this powerful tool to explore other novel electrode structures.
