Quality Assurance & Analytical Verification
At Shenghua Pharmaceutical, scientific integrity is our primary foundation. We eliminate ambiguity through rigorous batch-specific documentation, authenticated Certificate of Analysis (COA) dossiers, and transparent HPLC chromatograms.
Three Pillars of Scientific Reliability
Every batch is evaluated against strict analytical parameters before release.
Chromatographic Purity
Utilizing reversed-phase C18 analytical columns, each batch is tested under validated gradient systems to confirm that main peak area meets designated purity thresholds (≥98.0% or higher).
Mass Concordance
Electrospray ionization (ESI) and MALDI-TOF mass spectrometry confirm exact molecular weights against theoretical sequences, verifying absence of sequence deletion artifacts.
Batch Traceability
Every product vial carries a distinctive lot and batch code corresponding directly to archived retention samples and digital analytical dossiers available to clients upon request.
How to Read Our Analytical Certificates
Our Certificates of Analysis provide complete transparency into testing parameters. We display retention time, peak width, area integration, and UV detection wavelength (214 nm/280 nm) so researchers can verify purity independently.
