ALEXANDRIA, Va., Jan. 20 -- United States Patent no. 12,531,228, issued on Jan. 20.

"Ion cyclotron resonance separator apparatus and method of use thereof" was invented by W. Davis Lee (Rockport, Maine).

According to the abstract* released by the U.S. Patent & Trademark Office: "The invention comprises a method for separating ions, comprising the steps of: providing an ion cyclotron resonance separator with a longitudinal axis; applying a magnetic field gradient along a length of the longitudinal axis; passing a single fixed radio frequency radially across the longitudinal axis; and spatially separating the ions at mass-to-charge ratio resonance locations along a length of the longitudinal axis, where the magnetic field gradient is within...
