Abstract

Duty Cycle Electric Field Hadamard Multiplexing Ion Mobility Spectrometry Printed Circuit Board Mass Spectrometry
Structures for Lossless Ion Manipulations (SLIM) are a unique class of ion optic predominantly used for ion mobility spectrometry, though the ability to accumulate, store, and redirect ions in a seamless fashion opens numerous possibilities for gas-phase ion chemistry. Owing to its highly modular nature and planar architecture, SLIM is uniquely suited to realize highly customized experiments, though this possibility has been shallowly explored by few groups. In research settings, SLIM has demonstrated capabilities as a separation platform, activation cell, reaction vessel, and spectroscopic sample sequencer. Despite this, efforts to standardize or commercialize the experiment do not leverage these facilities for the end user. For SLIM to realize its potential as an ion chemistry platform, the access to custom experiments must be opened to other researchers, and a wider range of configurations must be explored. In this work, numerous alternative SLIM designs are developed, and tools for creating these alternatives are offered to other instrumentation researchers. Additionally, alternative methods for leveraging the lossless nature of SLIM are demonstrated in a custom build that enables 100% duty cycle ion mobility spectrometry.
