The ion transmission efficiency in mass filters depends markedly on mass-to-charge ratio, and this dependence also varies with the resolving power. This paper describes a very simple method for measuring there rative transmission efficiency without introducing test gases to a system. The method is based on the property of mass filters that ions of different mass-to-charge ratio have the same transmission efficiency at the poorest resolving power. Examples of the results are given. The results are compared with those measured by in troducing test gases.
