Certificate of Analysis for Research Peptides UK

A Certificate of Analysis is a document that records analytical information about a product batch, such as identity, purity and testing method. For researchers sourcing compounds from external suppliers, a COA provides an independent record of what has been tested, which analytical method was used and what result was recorded. At Light Peptide, COA access is treated as a baseline expectation — not an optional extra — in the research supply process.

High-performance liquid chromatography is commonly used to assess compound purity by separating and measuring components within a sample.

HPLC analysis allows researchers and suppliers to quantify the relative proportion of the target compound within a batch and identify the presence of impurities or degradation products. Where HPLC data is available, it is recorded within the Certificate of Analysis for that batch and made accessible through the Light Peptide COA Library.

HPLC is a purity assessment method. It does not constitute a therapeutic, medical or health-related claim. All products are supplied strictly for in-vitro laboratory research use only.

Batch traceability helps customers understand which product batch they are reviewing and supports a more transparent research supply process. 

When a researcher can link a Certificate of Analysis to a specific product batch, they gain confidence that the documentation they are reviewing corresponds to the exact material they are ordering. This connection between batch reference, analytical result and product listing is the foundation of responsible research supply.

At Light Peptides, batch references are recorded and COAs are aligned to product listings where documentation is available, allowing researchers to review relevant information before placing an order.
