Determination of NO_2~- and NO_3~- in Vegetable with Suppressed Ion Chromatography
Bibliographic record
Abstract
NO~-_(2)and NO~-_(3) were determined with the method of suppressed ion chromatography.Under the optimum chromatographic conditions,NO~-_(2) and NO~-_(3) could be well separated within 8 min.For NO~-_(2),the detection limit was 0.002 mg/L,relative standard deviation was 2.58 %,liear range 0.2 mg/L~20 mg/L,correlation coefficient 0.999 6.For NO~-_(3),the detection limit was 0.011 mg/L,relative standard deviation was 2.01 %,linear range 0.3 mg/L~30 mg/L,correlation coefficient(0.999 2).This method was applied to determine NO~-_(2)and NO~-_(3) in vegetables with good result.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
