Latest Patents

One of his latest patents is the "Complemented Ion Funnel for Mass Spectrometer." This patent describes a mass spectrometry method that involves introducing ions and gas into a first electrode section of an ion transport apparatus. The apparatus includes a second electrode section with stacked, mutually parallel ring or plate electrodes, along with an ion outlet aperture. The method provides non-oscillatory voltages to the electrodes, diverting the motion of ions towards the entrance aperture of the second electrode section. Additionally, it details the transportation of ions through the second electrode section to the vacuum chamber and the removal of gas through an exhaust port.

Another notable patent under his name is also titled "Complemented Ion Funnel for Mass Spectrometer." This patent outlines a method that introduces ions and gas into a first electrode section through a slot of an ion transfer tube. The apparatus is designed to ensure that the first longitudinal axis does not intersect with the outlet of the ion transfer tube. The method includes providing voltages to the electrodes that encourage ions to migrate towards the first longitudinal axis and exhausting gas through a port offset from the ion outlet aperture.
