Visualization of Streams of Small Organic Molecules in Continuous-Flow Electrophoresis
Bibliographic record
Abstract
Continuous-flow electrophoresis (CFE) separates a stream of a multi-component mixture into multiple streams of individual components inside a thin rectangular chamber. CFE will be able to benefit flow chemistry when it is capable of generically detecting streams of small organic molecules. Here we propose a general approach for molecular stream visualization via analyte-caused obstruction of excitation of a fluorescent layer underneath the separation chamber – fluorescent sublayer-based visualization (FSV). We designed and fabricated a CFE device with one side made of quartz and another side made of UV-absorbing visibly-fluorescent, chemically-inert, machinable plastic. This device was demonstrated to support non-aqueous CFE of small organic molecules and quantitative detection of their streams in real-time with a limit of detection below 100 µM. Thus, CFE may satisfy conditions required for its seamless integration with continuous flow organic synthesis in flow chemistry.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
