High duty cycle trapping ion mobility spectrometer |
| 摘要 |
The invention provides a trapping ion mobility analyzer and methods for operating the ion mobility analyzer. The trapping ion mobility analyzer comprises an RF field for radially confining ions along an axis, a region with an axial electric DC field and a gas flow along the axis counteracting the electric DC field in the region, wherein the region either comprises a rising edge with an increasing axial electric DC field or a falling edge with a decreasing axial electric DC field and wherein the slope of the electric field strength along the axis is not constant at a substantial portion of the edge. |

1. An ion mobility analyzer comprising an RF field for radially confining ions along an axis, a region with an axial electric DC field and a gas flow along the axis counteracting the electric DC field in the region, wherein the region comprises a rising edge with an increasing axial electric DC field or a falling edge with a decreasing axial electric DC field, characterized in that the slope of the electric field strength along the axis is not constant at a substantial portion of the edge. |
