Abstract

Rationale

In the development of quadrupole mass spectrometers, there is a growing interest in understanding the modified first stability region under conditions of unbalanced DC and RF voltages.

Methods

Based on the properties of the solution to the Dirichlet problem for the Laplace equation, the potentials on the orthogonal rod pairs of a quadrupole mass filter were determined. The trajectory method was employed to calculate the stability regions and transmission contours.

Results

The equations of ion motion were derived in the presence of DC and RF voltage amplitude imbalances. First stability region diagrams were constructed for conditions involving asymmetry in RF and DC voltage amplitudes, as well as RF phase shifts.

四极质量滤波器中驱动电压的不平衡。

原理：在四极杆质谱仪的发展中，人们对理解在不平衡直流和射频电压条件下修改的第一稳定区越来越感兴趣。方法：根据拉普拉斯方程狄利克雷问题解的性质，确定四极质量过滤器正交棒对上的电位。采用轨迹法计算稳定区域和传输轮廓。结果：导出了直流和射频电压幅值不平衡时离子运动方程。首先，针对射频和直流电压幅值不对称以及射频相移的情况，构建了稳定区域图。

期刊介绍： Rapid Communications in Mass Spectrometry is a journal whose aim is the rapid publication of original research results and ideas on all aspects of the science of gas-phase ions; it covers all the associated scientific disciplines. There is no formal limit on paper length ("rapid" is not synonymous with "brief"), but papers should be of a length that is commensurate with the importance and complexity of the results being reported. Contributions may be theoretical or practical in nature; they may deal with methods, techniques and applications, or with the interpretation of results; they may cover any area in science that depends directly on measurements made upon gaseous ions or that is associated with such measurements.
