1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

rationaleThe ion motion within a mass spectrometer is governed by the coupling of gas dynamics and electric fields. Therefore, a comprehensive understanding of ion transport from atmospheric pressure to the high-vacuum mass analyzer is crucial.

methodsIn this work, a hybrid computational fluid dynamics-direct simulation Monte Carlo (CFD-DSMC) strategy was employed to accurately resolve the cross-scale flow fields spanning from the continuum to the rarefied regime in the mass spectrometer. Subsequently, a multiphysics model integrating gas dynamics, electric fields, and ion trajectories was developed to achieve high-precision predictions of ion transport behavior.

resultsTo validate the accuracy of the theoretical simulation, ion transmission efficiencies of acetone and toluene were experimentally measured using a homemade low-pressure photoionization time-of-flight mass spectrometer (LPPI-TOF-MS). The experimental results demonstrated a strong correlation with the simulation predictions, achieving a maximum Pearson correlation coefficient (r) of 0.96 for toluene and 0.90 for acetone in the radio-frequency-only quadrupole (RFQ) region, confirming the model's reliability.

conclusionsThis study provides a robust theoretical tool for elucidating ion transport mechanisms and guiding the optimization of ion optics in mass spectrometers.
