Abstract
A solid phase extraction /ultra performance liquid chromatographic method was developed for the analysis of residues of 4- Chlorophenoxyacetic acid,5- Nitroguaiacolate,Thidiazuron and Forchlorfenuron in apple. Samples were extracted with 80% acetonitrile water solution,and then concentrated and cleaned up on a HLB solid phase column. The separation of target compounds was carried out on a BEH C18column( 2. 1mm ×50 mm,1. 7 μm) under gradient condition using methanol- 30 mmol /L NH4 Ac as the mobile phase. The recoveries ranged from 90. 1% to 95. 2% with the relative standard deviations of 1. 1%- 2. 4%. The detection limits of 4- chlorophenoxyacetic acid,5- nitroguaiacolate,thidiazuron and forchlorfenuron are 1mg /kg,1mg /kg,1mg /kg,and 0. 4 mg /kg,respectively. The developed method is simple and fast,and it can be used to detect four kinds of plant growth regulaters in apple.

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
