What are the standard testing methods for monk fruit powder purity?

HPLC analysis using NH2 column (250×4.6mm, 5μm) with mobile phase (acetonitrile:water=75:25) at 1.0mL/min flow rate. Detection at 210nm measures mogrosides III-V with ±1.5% measurement uncertainty (k=2). System suitability requires resolution ≥1.8 between mogroside V/VI peaks and RSD ≤2.5% for replicate injections.
