Breakthrough Parallel Mass Spectrometry Analyzes Billions of Molecules Simultaneously

Rockefeller University researchers unveiled MultiQ-IT, a parallel ion-trap mass spectrometer prototype that routes ions through hundreds of openings to analyze billions of molecules at once, boosting sensitivity and throughput by up to two orders of magnitude and enabling deeper single-cell proteomics and metabolomics—though it remains a proof-of-concept rather than a commercial instrument.
