Internal quality control

Product quality control depends on advanced testing instruments and high-level technical experts, the effective combination of the two can form a rapid and rigorous product quality control ability.

The laboratory is equipped with advanced and efficient detection equipment, which can detect conventional physical and chemical indexes, active ingredients (UPLC, HPLC, UV), solvent residues (GC), pesticide residues (GC-MS), melamine (HPLC), plasticizer (HPLC-MS), polycyclic aromatic hydrocarbons (GC-MS), unknown  (LC-MS-MS), harmful substances (ICP-MS), antioxidant value (enzyme reader), raw materials and products Identification (HPTLC, IR), irradiation residue (ppsl), enzyme activity, protein and microorganism were detected.
