Quality Control – Ensuring Catalyst Performance and Purity
At Shandong Xunda Chemical, quality control is an integral part of every stage in our catalyst production. We follow strict protocols to ensure each product delivers consistent performance, high purity, and long-term reliability for industrial applications.
Raw Material Verification
We source precious metals and chemical reagents only from certified suppliers. Every batch undergoes incoming inspection, including metal purity analysis by ICP-OES, moisture determination, and impurity screening. This prevents any deviation in catalyst composition from the very beginning.
Controlled Manufacturing Process
Production follows standardized operating procedures to ensure batch-to-batch consistency. Parameters such as temperature, pH, reaction time, and stirring speed are continuously monitored and recorded. Automated dosing systems reduce human error and improve process repeatability.
Comprehensive Product Testing
Each catalyst is tested for surface area, particle size distribution, precious metal content, and catalytic activity. We also perform selectivity and stability tests under simulated working conditions to ensure the catalyst meets the performance requirements of its intended application.
Analytical Instruments and Techniques
Our quality lab is equipped with ICP-OES, XRF, BET surface area analyzers, and particle size analyzers. These instruments allow us to detect trace impurities, verify metal dispersion, and confirm that physical properties remain within specification.
