Eeting Chem employs strict quality control methods for sodium pyrosulfite, benzonitrile and polyaluminium chloride to ensure compliance with global standards.
The raw materials were thoroughly screened and titrated by X-ray fluorescence spectrometry to eliminate impurities. Process inspection and monitoring of key variables with real-time fluctuations, such as the pH stability of polyaluminium chloride and the moisture content of sodium metabisulfite.
Final product confirmation: Determine the coagulation efficiency of polyaluminium chloride; The purity of benzonitrile determined by GC-MS technology is greater than 99.5%. The food-grade safety of sodium metabisulfite has been verified (FCC standard). The digital QC log can be used to track each batch and has passed the ISO 9001 certification.
