Quadrupole mass filters using non-sinusoidal driving potentials present exciting
opportunities for new functionality. Predicting figures of merit like resolving power and …

In this follow-up paper to our previous work on single analyzer precursor ion scans in a
linear quadrupole ion trap (Snyder, DT; Cooks, RG Single analyzer precursor ion scans in a …

The Paul trap with a rectangular driving field, known as digital ion trap (DIT) has been
investigated by mapping the stability diagram, ie, measuring the relative storage efficiency …

Since their introduction, digital quadrupole mass spectrometers have described by analogy
to traditional sinusoidal devices. However, digital quadrupoles exhibit unique behaviors and …

Cooling of ions or other charged particles in electromagnetic traps is an essential tool to
achieve control over their degrees of freedom on the quantum level. For many objects, there …

Digital waveform technology allows the waveform frequency and duty cycle to be instantly
changed. These sudden changes affect ion motion and hence ion energy. Mass …

Accurate nanoparticle mass characterization is a challenging task, especially at a single
particle level. To solve this problem, a strategy for the mass measurement of single intact …
