Living with the philosophy and policy of “there is no substitute for quality”, Auropure places rigorous quality checks throughout the manufacturing process at every step, from the selection of raw materials to the testing of final products. These checks mainly include:

- Identification (HPTLC, HPLC, GC)

- Assay (HPLC, UV, GC)

- Microbiologic

- Pesticide residues (GC-MS screen & quantification for 281 items)

- Solvent residues (GC-HS & FID)

- Heavy metals (ICP-MS & AAS)

- Aflatoxins (HPLC-FLD on B1, B2, G1, G2)

- PAHs (SPE-HPLC-FLD, 15 items)

To the natural products like herbs and extracts, our quality control involves not only full-item analysis to specifications, but also the botanical origin identification, batch-to-batch consistency and effectiveness potency, which are important factors to our customers who take our ingredients into their products.
