MultiQ-IT Prototype Handles 10 Billion Charges at Once, Lifting Mass Spectrometry Sensitivity 100-Fold
1 articles · Updated · SciTechDaily · Jun 5
Summary
A MultiQ-IT prototype held up to 10 billion charges simultaneously in tests, shifting mass spectrometry from sequential analysis toward massively parallel processing.
A 486-port version delivered about 1,000 times the capacity of conventional ion traps and improved signal-to-noise ratios by up to 100-fold, helping reveal rare proteins that standard systems can miss.
The design replaces a traditional ion-trapping component with a cube-shaped chamber of electrically controlled openings; ions are split into parallel streams, while a small voltage barrier lets common singly charged background ions escape.
Scaled from 6 openings to 1,134 ports, the proof-of-concept draws on nuclear pore biology and aims to support single-cell proteomics, metabolomics and faster drug discovery, though it is not yet a commercial instrument.

Overview
The MultiQ-IT prototype marks a major leap in molecular analysis by introducing a cube-shaped ion-trapping chamber with hundreds of electrically controlled openings. This new design replaces a key part of traditional mass spectrometers, allowing ions to interact with gas molecules, slow down, and move randomly inside the chamber. Unlike older instruments that process ions one group at a time, MultiQ-IT can sort, hold, and direct multiple groups of ions at once. This shift from sequential to simultaneous processing greatly increases efficiency and sets a new standard for speed and depth in molecular analysis.
