20100237233 | ION OPTICS DRAIN FOR ION MOBILITY - A sample analysis system incorporates an ion removal mechanism for removing residual ions from the sample analysis system. The ion removal mechanism can be included in an ion optics assembly, which connects an ion mobility filter to a mass analyzer.
