"mass spectrometers process ions sequentially, overcome replacing core ion-trapping chamber with cube-shaped device having >1K electrically controlled openings... electrical voltage barriers let abundant background molecules leak out while trapping rarer, information-rich molecules, improving signal-to-noise ratio as much as 100X... tracking 1,000s chemical reactions simultaneously, structural biology, reading single cell's full protein content where rare molecules often drowned out by abundant ones"
