Abstract
A capillary electrophoresis-based method was developed for the detection of phosphate in small samples. Phosphate was incubated in buffer with 50 μM Eu3+-tetracycline to allow for the formation of the luminescent Eu3+-tetracycline-phosphate complex. The complex was separated from the excess Eu3+-tetracycline, which is also luminescent, and the complex detected by post-column laser-induced luminescence within a sheath flow cuvette. Separation time was <90 s with a total run time of 5 min. No flushing of the capillary was required between runs. Phosphate standards ranging from 10–200 μM were analyzed. Increasing the concentration of Eu3+-tetracycline increased the linear range but at the cost of a decreased sensitivity. A decrease in the Eu3+-tetracycline resulted in an increase in sensitivity down to 5 μM but a decrease in linear range. As an application, the phosphate content of a milligram sample of soil was determined to be 0.51 ppm.

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
