Abstract
A size exclusion chromatography (SEC) followed by post-column reaction with iodide and electrochemical detection method is developed for analysis of total organic and inorganic chloramines. Ammonium chloride and a group of test compounds (Glycine, Tyrosine, DL-Alanyl-DL-Alanine, Arg-Gly-Asp-Ser, Bradykinin, Aprotinin, and alpha-Lactalbumin) are selected and chlorinated to represent inorganic chloramines and different sizes of organic N-chloramines. An analytical SEC column with pore size of 60A is used and chromatographic conditions including the working electrode potential and flow rate are optimized to gain optimum resolution and sensitivity. The detection limits are estimated to be 0.12 mg/L and 0.05 mg/L, respectively, for tested inorganic and organic chloramines.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
