Quality Control

Botanical extracts must be standardized with strict quality controls to ensure consistent composition, safety, and potency. All the botanical extracts manufactured by Quality Herb undergo a comprehensive series of tests for identity, purity, and potency using international standards or in-house methods.

Our well-trained staff is dedicated to ensuring that all our products meet these standards before they are released for sale.

Our certificate of analysis includes standard results for marker compounds, heavy metals, pesticides, solvent residues, microbe, mesh distribution, and bulk density. Additional testing can be done at the customer's request.

We could arrange the following tests to ensure the quality of our supplier's products:
Species Identification (TLC, IR, HPLC)
Pesticide Residue Analysis (GC-C MS, HPLC, LC-C MS)
Heavy Metal Analysis (ICP-C MS)
ID Components Control ( HPLC, GC-C MS, LC-C MS, UV-CVIS)
