Принадлежит:

The invention provides an ion funnel device for low-mass-to-charge-ratio ion transmission and a use method of the ion funnel device. According to the invention, a plurality of transmission electrodes and spacing elements are arranged at intervals, the axial potential barrier is reduced by unequal electrode spacing, and the ion beam is limited by gradually reducing electrode holes; meanwhile, the spacing element and the adjacent electrode are arranged to be non-airtight, so that the lower-stage vacuum load is reduced; according to the device, the electrode distance is reduced, the number of electrodes is sharply reduced, the load capacitance value is low, the drive circuit requirement is greatly reduced, and assembling is easy. According to the application method provided by the invention, charged ions are transmitted to a next-stage mass spectrum device by using radio frequency voltage and a direct-current gradient electric field, and radio frequency voltage with a phase difference of 180 ...
