Method for transmitting ions and carrier gas between mutually facing curved electrodes |
| 摘要 |
A method for transmitting ions entrained in a flowing carrier gas into and through a gap defined by a pair of mutually facing curved electrodes comprises: inputting the ions and flowing gas into the gap through an ion inlet orifice of a first one of the pair of electrodes, the ion inlet orifice comprising an orifice wall, an orifice inlet end and an orifice outlet end, the orifice wall being smoothly convexly curved between the inlet end and the outlet end, wherein a width of the gap and a flow rate of the carrier gas through the ion inlet orifice and gap are such that the gas flow is laminar within the ion inlet orifice and gap. |

1. A method for transmitting ions entrained in a flowing carrier gas into and through a gap defined by a pair of mutually facing curved electrodes, the method comprising:
inputting the ions and flowing gas into the gap through an ion inlet orifice of a first one of the pair of electrodes, the ion inlet orifice comprising an orifice wall, an orifice inlet end and an orifice outlet end, the orifice wall being smoothly convexly curved between the inlet end and the outlet end, wherein a width of the gap and a flow rate of the carrier gas through the ion inlet orifice and gap are such that the gas flow is laminar within the ion inlet orifice and gap. |
