Abstract
A small-sized, high-resolution, time-of-flight (TOF) mass spectrometer has a closed ion orbit formed by plural electric sectors. Ions can make plural revolutions in the closed orbit. An entrance path is formed in the closed orbit to introduce ions into the closed orbit. An exit path is formed in the closed orbit to take ions from the closed orbit. The entrance and exit paths can be formed at the exit and entrance of the electric sectors forming the closed orbit or can be positioned in the orbit between the electric sectors forming the closed orbit.
