Modeling of an ion source lens system for sensitivity enhancement in a non-scanning linear ion trap

- We present experimental selective mass isolation for a linear ion trap (LIT) operating in a non-scanning mode.
- Ion source lens system (ISLS) coupled to a non-scanning LIT was simulated using CPO program.
- Simulation study of ion injection, trapping and ejection was done to optimize LIT sensitivity.
- Our results have shown that an optimized ISLS can improve LIT sensitivity by a factor of 4 compared to commercial ion source lens systems.
