摘要：

We consider the case of a generalised quadrupole mass spectrometer in which a static magnetic field is applied to the body of the filter. We have solved numerically the extended Mathieu equation numerically constructing a theoretical transmission mass spectrum. The analysis shows for what values of the parameters an enhancement of the quadrupole resolution is achieved. Initial experimental results for argon confirm the predicted theoretical trends.
