A chromatogram screenshot is not the complete lab record

Read beyond the final result

A peptide COA may include a chromatogram, but that picture is only part of the evidence behind the result. FDA's laboratory-records Q&A explains that a printed chromatogram generally omits information needed to reconstruct the analysis.

Four useful takeaways

• The injection sequence may not appear on the printout.
• Instrument and integration methods are separate supporting records.
• The audit trail can contain information missing from the final image.
• A printout can help reviewers, but pharmaceutical laboratories must retain the underlying electronic records.

FDA Records and Reports Q&A, question 4

Put the evidence in context

Ask what supporting records the laboratory retains and can explain. Do not assume a polished graph is the entire analysis. Missing public raw data does not prove manipulation.

This source addresses pharmaceutical production. It does not certify research peptides or establish product safety, efficacy, approval, or suitability for human use. We make no allegation about any vendor.
