Identity evidence
Request a suitable identity method and report, such as mass spectrometry where appropriate, with the material and batch clearly identified.
A specification-led quality review.
Connect your requested peptide with the supplier’s evidence. Define the required checks before an order is agreed.
Four questions guide the review.
WANZE coordinates documents and supplier follow-up. Testing scope and third-party laboratory work are agreed for each project.
Discuss your specificationIdentity & specification
Record the requested name, variant, sequence or identifier, form and acceptance criteria. Clarify ambiguities before a supplier quote is treated as comparable.
Supplier & document source
Clarify the supplier’s role and the issuer of each document. Request the report scope, dates and laboratory details where relevant.
Batch consistency
Compare the product, lot reference and dates across the COA, label and offered material. Resolve mismatches before order approval.
Sample & independent review
Agree whether a sample or an independent laboratory review is needed, who arranges it and which criteria determine acceptance.
Specify the evidence you need.
The required analytical package depends on your material and project. These are document requests to discuss, not claims that every product has been tested.
Purity evidence
Ask which method supports the stated purity, its scope and any underlying chromatogram. A percentage without context is incomplete.
Project-specific tests
Include additional requirements such as water content, residual solvents or microbiological criteria when relevant to your specification.
Bring your quality requirements into the brief.
Share required methods, acceptance criteria and any independent testing needs.
