Map your testing records
Create a documentation workflow for HPLC, LCMS, COAs, and batch files.
Request testing supportWhere HPLC fits in documentation
HPLC is commonly used in purity documentation. For brand operators, the key is linking the report to the right lot and recording review decisions.
Chromatogram records
Keep chromatogram files and summary results with the product batch they support.
Review limits
Use HPLC language carefully and keep it tied to documentation and quality control context.
Where LCMS fits in documentation
LCMS is commonly used for mass confirmation records and can complement purity documentation when connected to the correct batch file.
Mass reference alignment
Confirm the sample, product name, lot code, and report fields match the internal record.
Combined files
Store LCMS records with COAs, supplier documents, and release notes.
How to use both in a COA workflow
Brands should define when reports are requested, how they are reviewed, where they are stored, and how approved documents become customer-facing.
Batch matching
Every report should map to one product batch and inventory release decision.
Publishing discipline
Customer-facing summaries should stay focused on documentation, testing method references, and certificate access.

Additional notes
HPLC in peptide documentation
HPLC is commonly used to discuss purity profiles and chromatographic results. Operators should connect HPLC references to the right batch and avoid overstating what the report proves.
LCMS in peptide documentation
LCMS is commonly used to discuss mass confirmation. It can complement purity documentation when the records are clear, batch-specific, and stored in the quality file.
Using methods responsibly
Testing method pages should educate about documentation workflows and stay focused on testing documentation, batch records, and research supply quality files.
FAQ
Is HPLC better than LCMS for peptides?+
They are different methods used for different documentation questions. Many brands evaluate how both can support batch records and COA review.
Can testing documentation replace a quality workflow?+
No. Testing documentation is one part of a broader workflow that includes supplier files, COAs, review decisions, labels, and fulfillment records.
