The whole process

Released by lot, with its certificate

A lot of this product is not supplied until it is tested. Release is a decision against a written specification, taken once per lot.

  • The lot is tested for purity by HPLC and for pH.
  • Results are compared against the specification, not against the previous lot.
  • A lot that does not meet the specification is not released.

Each lot is released against a written purity specification. The result for a lot is on its certificate.

Purity is confirmed by an independent third-party laboratory alongside our own release testing.
