Latest Patents

One of Cheung's latest patents is focused on heat management for inductively coupled plasma systems. This invention includes a system for cooling an inductively coupled plasma (ICP) instrument, which consists of the ICP instrument, a pump in fluid communication with the instrument via a first conduit, and a micro-channel heat exchanger in fluid communication with the instrument via a second conduit. The pump is designed to generate a pump outlet pressure of coolant that exceeds the back pressure of the instrument, ensuring efficient cooling. The pressure of the coolant traveling through the second conduit and into the heat exchanger is maintained at or below 5 pounds per square inch (psi) above atmospheric pressure.

Another significant patent by Cheung involves curved ion guides and related systems and methods. This invention features an ion guide that includes a plurality of curved electrodes arranged along a curved central axis. The electrodes define a curved ion guide region, which begins at an ion entrance and ends at an ion exit. The ion guide is equipped with an ion deflecting device that applies a radial DC electric field across the ion guide region. The radius of curvature of the ion guide region varies along the central axis, maximizing at the ion entrance and decreasing toward the ion exit.
