Quality Assurance

Every Batch Tested. Every Shipment Verified.

GMP Production Management System

Our comprehensive quality control system covers every stage from raw material intake to final product release.

01

Raw Material Inspection

All incoming raw materials undergo strict identity and purity verification before entering production.

02

In-Process Control

Continuous monitoring of reaction parameters — temperature, pressure, pH — throughout the synthesis process.

03

Finished Product Testing

Comprehensive analysis of purity, free phenol, moisture, heavy metals, and other critical parameters.

04

COA Issuance & Release

Independent COA report generated for each batch before shipment approval and dispatch.

Professional Analytical Laboratory

Our in-house laboratory is equipped with precision analytical instruments for comprehensive physicochemical testing. Every parameter — from purity to heavy metal content — is rigorously verified before product release.

HPLC (High Performance Liquid Chromatography) — Purity analysis and impurity profiling
Melting Point Apparatus — Precise melting range determination
Karl Fischer Moisture Titrator — Accurate moisture content measurement
Atomic Absorption Spectrophotometer — Heavy metals detection (Pb, Fe, etc.)
UV-Vis Spectrophotometer — Quantitative analysis and identification
Analytical Balance (0.0001g) — Precision sample weighing
