Bubble preconcentration coupled with SALDI-TOF MS for rapid detection of PFAS in environmental water.

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
Per- and polyfluoroalkyl substances (PFASs) are highly persistent and bioaccumulative contaminants that pose serious ecological and human health risks even at trace levels. In this study, we developed a rapid and eco-friendly bubble preconcentration-surface-assisted laser desorption/ionization time-of-flight mass spectrometry (SALDI-TOF MS) method for PFAS detection in water. Compared with our previous design, the average bubble size was reduced from 312 to 243 μm, enhancing the enrichment of short-chain PFASs. Using an iron-based metal-organic framework (MIL-101(Fe)) as the assisting material, the method achieved enrichment ratios of 700-fold for PFOS and 400-fold for PFHxS within 30 s. The entire analysis is completed within minutes without organic solvents, offering substantial reductions in time and waste compared with conventional SPE-LC-MS/MS. PFOS concentration of ~3 ng/L was detected in Tamsui River samples, consistent with LC-MS/MS results. This solvent-free, small-bubble-based method provides a sustainable approach for rapid PFAS monitoring in environmental waters.
