The applications of phase space dynamics in quadrupole mass spectrometry have led to better understanding of ion motion and stability. One application is its use in determining ion beam acceptance and transmission of quadrupole mass filters. One way of determining acceptance is the method of ellipses. This method is relatively simple and does not require exhaustive amounts of calculation. In this tutorial Special feature article, Peter Reilly and colleagues present a computational method to investigate elementary differences between digital and sinusoidal systems. Peter Reilly is Associate Professor of Chemistry at Washington State University (Pullman, WA). His primary research focus is to develop new instrumentation and techniques to extend the working range of mass spectrometry. He is one of the world leaders in the development of digital ion traps and ion guides.

正弦和数字离子导向器的接受和传输的教程和综合计算研究

相空间动力学在四极杆质谱中的应用使人们对离子运动和稳定性有了更好的了解。一种应用是将其用于确定四极质量过滤器的离子束接受度和透射率。确定接受程度的一种方法是椭圆法。此方法相对简单，不需要详尽的计算量。在本专题专题文章中，Peter Reilly及其同事介绍了一种计算方法，以研究数字系统与正弦波系统之间的基本差异。彼得·赖利（Peter Reilly）是华盛顿州立大学（华盛顿州普尔曼分校）的化学副教授。他的主要研究重点是开发新的仪器和技术，以扩展质谱仪的工作范围。
