Prolate trochoidal mass spectrometer
Deprecated: cycloidal mass spectrometer.

Mass spectrometer in which the ions of different m/z are separated by means of crossed electric and magnetic fields in such a way that the selected ions follow a prolate trochoidal path.

Prolate trochoidal mass spectrometer

A mass spectrometer in which the ions of different mass/charge ratios are separated by means of crossed electric and magnetic fields in such a way that the selected ions follow a prolate trochoidal path. The commonly used term “cycloidal” is incorrect and should not be used as the path is not cycloidal. (A cycloid is a special case of a trochoid). See crossed electric and magnetic fields.

Prolate trochoidal mass spectrometer

http://goldbook.iupac.org/P04874.html

A mass spectrometer in which ions of different mass/charge are separated by means of crossed electric and magnetic fields in such a way that the selected ions follow a prolate trochoidal path. The usual term 'cycloidal' used sometimes is incorrect because the path used is not cycloidal. A cycloid is a special case of a trochoid.
