Despite many potential applications, miniature mass spectrometers have had limited
adoption in the field due to the tradeoff between throughput and resolution that limits their …

Ambient ionization techniques provide a way to sample materials via creation of ions in the
air. However, transferring and focusing of these ions is typically done in the reduced …

In 1938, Walker Bleakney and John A. Hipple first described the cycloidal mass analyzer as
the only mass analyzer configuration capable of “perfect” ion focusing. Why has their …

Spatial aperture coding is a technique used to improve throughput without sacrificing
resolution both in optical spectroscopy and sector mass spectrometry (MS). Previous work …

With the advent of technologies such as ion array detectors and high energy permanent
magnet materials, there is renewed interest in the unique focusing properties of the cycloidal …

Cycloidal sector mass analyzers have, in principle, perfect focusing due to perpendicularly
oriented uniform electric and magnetic fields, making them ideal candidates for …

Mass spectrometers are essential instruments for in situ analysis of planetary materials.
Ideally, a space flight mass spectrometer would have a mass range from∼ 10 u to at least …

Rationale Higher resolution in fieldable mass spectrometers (MS) is desirable in space flight
applications to enable resolving isobaric interferences at m/z< 60 u. Resolution in portable …

This work compares the coded aperture imaging performance of thermionic filament and
carbon nanotube (CNT) field emitter-based electron sources in cycloidal-coded aperture …

Cycloidal mass analyzers are unique sector mass analyzers as they exhibit perfect double
focusing, making them ideal for incorporating spatial aperture coding, which can increase …
