An improved ion detector having a removable ionizer inlet assembly, a high vacuum chamber, an analyzer and a removable detector are provided. Valves are employed to permit replacement of the ionizer inlet assembly or the detector without meaningful loss of vacuum. The ionizer inlet assembly has a gap which is adjustable in order to permit more precise control of the molecules which are delivered to the ionizer. Adjustment is provided to control ions which are discharged from the ionizer assembly prior to delivery to the analyzer. Internal heating is provided for the ionizer inlet assembly zones. The ionizer preferably has generally longitudinally oriented slots to facilitate more efficient electron bombardment of the molecules.
