Abstract
A portable mass spectrometer including an ion source, an ion detector, and a Loeb-Eiber style high-pass ion separator comprising an array of wires. The array can have first and second sets of wires where the distance between adjacent wires is less than the diameter of each of the wires. An electrical generator can be configured to create an electrical current and supply the electrical current to the first set of wires while the second set of wires remains grounded.
