A MASS SPECTROMETER SYSTEM HAVING AN EXTERNAL DETECTOR

摘要

A mass spectrometer system is disclosed. The mass spectrometer includes a vacuum chamber defining an enclosed evacuated space and an ion trap disposed in the enclosed space. The ion trap is configured to trap an ionized sample. The mass spectrometer further includes an son detector coupled to the chamber at a location external to the chamber such that sample ions may exit the evacuated space and into the externally-coupled detector without loss of vacuum pressure.
