Analytical methods

Where a United States Pharmacopeia chapter or ICH guideline applies, the analysis follows it and the certificate cites it. Other analyses are described on the certificate by technique and conditions.

Chain of custody

Identification at submission

Each lot is assigned a sample ID when the submission is placed. The ID is printed on the packet and marked on every vial before shipment.

Reconciliation on receipt

Vials are reconciled against the packet on arrival and receipt is confirmed to the client. Analysis begins once every lot in the submission has been received.

Recorded milestones

Receipt, start of analysis and certificate release are recorded against the submission and stated on the certificate.

Certificate integrity

Unique certificate ID

Every certificate carries an ID tied to one lot and one submission, with a QR code that opens the verification record.

Document fingerprint

A SHA-256 hash of each certificate is recorded at release and shown on the verification page, so any altered copy can be identified.

Issued copy on record

The certificate as released is retained by the laboratory and can be retrieved from the verification page at any time.

Reporting policy

Results are reported exactly as measured, with the specification beside each one. A lot that does not meet specification receives a certificate in the same format as a conforming lot, with the conclusion stated on the first page.

The fee for an analysis is independent of its outcome. A certificate reports analytical results for the lot tested; it is not a regulatory approval and does not state that a product is suitable for any use.
