Abstract
A high performance capillary zone electrophoresis method was established for the determination of tamsulosin and the related substances in its bulk drug and sustained release capsules. An uncoated fused-silica capillary(75 μm i. d. × 60 cm,effective length 50cm) was used,with 20 mmol / L borate solution( pH7. 30) as running buffer at the detection wavelength of 230nm. And the injection volume of sample was kept for 10 s at 3. 4kPa. The separation voltage was set 15kV at 25 ℃. Tamsulosin and the related substances were separated well within 7 min. The calibration curves for tamsulosin,( R)- 5-( 2-aminopropyl)- 2-methoxybenzenesulsonamide and 2-(2-ethoxyphenoxy) ethyl bromide were good linear in the range of 10. 28 ~ 123. 4 μg / mL(r =0. 9995),14. 99 ~179. 9μg /mL(r =0. 9993) and 8. 496 ~101. 9μg /mL(r =0. 9987), respectively. Their average recoveries were 100. 9%,100. 1% and 99. 2%,respectively. And their relative standard deviations(RSD)were all less than 2. 9%. The method is proved to be specific,fast,accurate,cheap and convenient. So the proposed CZE method can be used for determining tamsulosin and related substances in its sustained release capsules. It will also be a reliable way to monitor for synthesis process of tamsulosin.

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
