Abstract

A novel design for a time-of-flight mass spectrometer capable of tandem mass spectrometry measurements with high resolution and high sensitivity using two variable reflectrons in a co-linear geometry. Variably switched reflectrons are oriented coaxially on opposing ends of the ion flight region allowing multiple passes of the ions along the flight region permitting high resolution, tandem mass spectrometry experiments to be performed. An electrostatic particle guide is incorporated to ensure high ion transmission efficiency in a multi-pass system. In addition to permitting the high transmission efficiency of ions, the EPG can be used in a bipolar pulsed mode to isolate ions of interest for structural study.
