Ion manipulations in structures for lossless ion manipulations (SLIM): computational evaluation of a 90° turn and a switch

The process of redirecting ions through 90° turns and 'tee' switches utilizing Structures for Lossless Ion Manipulations (SLIM) was evaluated at 4 Torr pressure using SIMION simulations and theoretical methods. The nature of pseudo-potential in SLIM-tee structures has also been explored. S...

Zusammenfassung:The process of redirecting ions through 90° turns and 'tee' switches utilizing Structures for Lossless Ion Manipulations (SLIM) was evaluated at 4 Torr pressure using SIMION simulations and theoretical methods. The nature of pseudo-potential in SLIM-tee structures has also been explored. Simulations show that 100% transmission efficiency in SLIM devices can be achieved with guard electrode voltages lower than ∼10 V. The ion plume width in these conditions is ∼1.6 mm while at lower guard voltages lead to greater plume widths. Theoretical calculations show marginal loss of ion mobility resolving power (
