Selectivity Beyond Mass: Real-Time Isomer Separation Using SLIM IMS Coupled to PTR-MS.
Article in Journal of mass spectrometry : JMS, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
Proton-transfer-reaction-mass spectrometry (PTR-MS) provides real-time analysis of volatile organic compounds (VOCs) relevant to atmospheric research, food and flavor characterization, industrial process control, and medical applications. However, PTR-MS is inherently limited in its ability to resolve isomers of molecules with the same mass-to-charge ratio (m/z). To address this selectivity constraint, we coupled a time-of-flight (TOF) based PTR-MS setup with a "Structures for Lossless Ion Manipulations Ion Mobility Spectrometry" (SLIM IMS) module. The integration of SLIM IMS introduces an additional separation dimension without compromising the real-time capability of PTR-MS. A custom designed SLIM device enabled efficient confinement and transmission of low mass ions (m/z < 300), which are typically analyzed in PTR-MS. The developed system achieved helium-based ion mobility resolutions (CCS
