A U.S. Patent for a “High-Throughput Cryogenic Spectroscopy for Glycan Analysis” was awarded to Ecole Polytechnique on December 31st, 2019. The present invention is a method for analyzing a plurality of molecules with cryogenic vibrational spectroscopy including the steps of providing a packet of molecules in a ionized form, injecting the packet into an ion mobility section, spatially separating the ions of the packet into subpackets according to their collisional cross section (CCS), recompressing the subpackets, by removing an empty space between them, loading the ions into a cryogenic ion trap… Learn More
