Abstract
Linear mode, reflectron mode, and multi-turn are techniques for m/z analysis in time-of-flight mass spectrometry. Reflectron mode and multi-turn enable analysis to be performed with a higher mass resolving power than that attained with linear mode. In this commentary, starting from the basic principles of time-of-flight mass spectrometry in linear mode, the possible improvements in mass resolving power that can be made by reflectron mode and multi-turn techniques will be explained.
