Latest Patents

Ledford holds a patent for a "Method and apparatus for mass spectrometric analysis at ultra-low." This invention features a trapped ion cyclotron resonance mass spectrometer that includes an analyzer cell with upper, lower, side, and end electrodes. These electrodes are strategically positioned to create a uniform electric field. The design incorporates a magnet to generate a magnetic field and irradiating wires adjacent to the electrodes to produce an RF alternating field. The electrodes are shaped as a rectangular hyperbola, which helps in creating a homogeneous quadrupolar electrostatic field. Sample ions are generated through reactions with reagent ions and are subsequently trapped by the electric and magnetic fields. The magnetic field causes the trapped ions to orbit at a frequency that correlates with their charge-to-mass ratio. The analyzer cell is then subjected to an alternating electric field, accelerating the ions until they collide with the upper and lower electrodes, where they are collected. An electrometer connected to these electrodes measures the current produced by the collected ions.
