Abstract
An ion detector includes: a first electron multiplier for detecting first ions having a first polarity; a second electron multiplier for detecting second ions having a second polarity different from the first polarity; a first anode for capturing electrons emitted from the first electron multiplier; a second anode for capturing electrons emitted from the second electron multiplier; and a switching circuit including a first input terminal electrically connected to the first anode, a second input terminal electrically connected to the second anode, and an output terminal, the switching circuit selectively connecting one of the first input terminal and the second input terminal to the output terminal.

An ion detector comprising:
- a first electron multiplier configured to detect first ions having a first polarity;
- a second electron multiplier configured to detect second ions having a second polarity different from the first polarity;
- a first anode configured to capture electrons emitted from the first electron multiplier;
- a second anode configured to capture electrons emitted from the second electron multiplier;
- and
- a switching circuit including a first input terminal electrically connected to the first anode, a second input terminal electrically connected to the second anode, and an output terminal, the switching circuit being configured to selectively connect one of the first input terminal and the second input terminal to the output terminal.
