How to read a peptide COA before placing a research order
A practical checklist for matching product, batch, purity and identity records.
Match the product and batch
Start with the exact product name, batch reference and format. A document should be clearly connected to the material being quoted.
Read the reported methods
Review which analytical methods are reported, including HPLC purity and any identity information. Ask the supplier to clarify the source of each record.
Keep the record with the order
Store the COA, quotation and batch reference together so a repeat order can be checked against the same information.
