Testing Methods & Standards
Chromatographic Analysis
HPLC and GC-MS analysis for purity, impurity profiling, and molecular identification per USP and EP standards.
Wet Chemistry
Classical titration, gravimetric, and colorimetric methods for assay determination and limit testing.
Physical Testing
Comprehensive physical property measurement including viscosity, density, refractive index, and particle size distribution.
Stability Studies
Long-term and accelerated stability testing per ICH guidelines ensuring product quality throughout shelf life.
Quality Without Compromise
Complying with national GB standards and international industrial specifications, the company provides complete inspection reports and SDS documents for every shipment. It continuously optimizes quality control workflows through internal audits and practical production feedback, ensuring stable qualification rate for gasoline, jet fuel, PP, PS, SBS and other products for domestic and Southeast‑Asian purchasers.
