Everything needed to understand what documentation is available, how to request it, and how our process works — before placing an order.
Certificates of Analysis
A Certificate of Analysis (CoA) is a document that records what was assessed for a given material and the results recorded against the methods used. Where a CoA is available for a product, it may be requested by quoting the catalogue identifier shown on the product page.
Analytical Methods Overview
Analytical documentation, where it applies to a product, typically references one or more identification and purity methods. The two most common in peptide documentation are high-performance liquid chromatography (HPLC) and mass spectrometry (MS). We describe these methods in plain language below. We do not state that every product is tested by the same methods — applicable documentation is described per product and provided on request.
HPLC Information
High-performance liquid chromatography separates the components of a sample so that the proportion attributable to the target compound can be estimated. In peptide documentation, an HPLC result is commonly reported as a purity percentage against the separation method used. The method conditions matter when interpreting a figure, which is why they are recorded on the documentation rather than summarised as a single marketing claim.
Mass Spectrometry Information
Mass spectrometry supports identity confirmation by measuring the mass-to-charge ratio of a compound, which can be compared against the expected mass of the target peptide. It answers a different question from HPLC: identity rather than relative purity. Where MS documentation applies to a product, it is provided as part of the documentation on request.
Batch & Lot Traceability
A lot (or batch) reference associates a specific production run with its documentation. For laboratory procurement this supports reproducibility, record-keeping and audit trails, and makes it possible to re-order with consistency. Lot referencing is applied where applicable.
Product Documentation Requests
To request documentation, use the documentation request form and quote the catalogue identifier for the product (for example, the identifier shown on each product page). Indicate which documents you need — for example a CoA — and the relevant lot if known.
Quality & Testing Policy
Our policy is to describe analytical and quality documentation accurately, per product, and to avoid blanket claims that are not substantiated for a specific item. Read the full Quality & Testing policy.
Research-Use-Only Policy
All materials are supplied strictly for legitimate laboratory, analytical, in-vitro and non-clinical research. They are not for human or veterinary use, consumption, administration, diagnosis, treatment or any clinical purpose. See the full Research-Use-Only Terms.
Shipping & Fulfilment Information
Dispatch timing, packaging and delivery expectations are set out in the Shipping Policy.
Procurement & Invoice Information
Tax invoices, bulk pricing enquiries and repeat-order support are available to laboratory and institutional buyers. See Procurement & Bulk Orders.
