Antonelli, Terry, Stout & Kraus, LLP.
Ion trap, mass spectrometer, and ion mobility analyzer
A compact, low-cost, and simple ion trap capable of operating at a low vacuum level is provided along with technology for utilizing that ion trap to perform mass spectroscopy and analyzing ion mobility without a drop in measurement accuracy. Ions are trapped in a one dimensional potential formed by a potential comprised of a direct current voltage and a potential comprised of an alternating current voltage. The trapped ions are made to collide with an electrode by changing at least the applied direct current voltage or alternating current voltage, and are detected as an electrical current value.
