摘要：

Resolution enhancement in linear time-of-flight mass spectrometry is demonstrated for a new technique, post-source pulse focusing. The relatively simple procedure followed to perform pulse focusing is described including a discussion of the need to choose proper experimental conditions. A resolving power of ca. 1500 for m/z 228 is demonstrated. Finally, equations are presented which allow the electric field conditions necessary for optimum pulse focusing to be estimated for instruments with a wide range of instrumental configurations.
