BioPepSyn Lab | COA and HPLC Review Checklist Version: 2026-10-20 | Editable document-review worksheet Source: https://biopepsynlab.com/resources/coa-hplc/ Use this worksheet to compare an actual report with the written specification for a research procurement project. Record the reported field and evidence; do not fill a missing result with an assumed pass. A completed worksheet is not a COA, laboratory test, certification or independent product release. REVIEW RECORD Project / quotation reference: ____________________________________________ Reviewer / date: __________________________________________________________ Supplier / issuing laboratory: ___________________________________________ Client / sample owner named on the original report: _______________________ Supplier's relationship to that client and supporting record: ______________ __________________________________________________________________________ Report title / report number / file version: ______________________________ Report issue date / sample test date: _____________________________________ Written specification / revision / date: __________________________________ Report status: [ ] report supplied [ ] not supplied [ ] test not performed [ ] requested field not reported [ ] not applicable, reason: __ Clarification / evidence reference: ________________________________________ 1. IDENTIFY THE MATERIAL AND THE DOCUMENT Exact product name / sequence or catalog reference: _______________________ __________________________________________________________________________ Material format and unit under review: ____________________________________ Nominal amount / formulation stated in the report: _________________________ Same product, formulation and nominal specification as the quote? __________ __________________________________________________________________________ Report lot / batch reference: _____________________________________________ Quoted lot / batch reference: _____________________________________________ Supplied lot / batch reference, if available: ______________________________ Sample identifier / source / collection date, if stated: ___________________ __________________________________________________________________________ Retained-sample identifier / linked lot / retained quantity, if required: __________________________________________________________________________ Retained-sample storage conditions / retention period / access or re-test arrangements, if agreed: __________________________________________________ Report scope: [ ] current batch [ ] historical batch [ ] sample example [ ] scope not yet confirmed Evidence linking report, sample and supplied batch: ________________________ __________________________________________________________________________ Verification reference supplied by the issuing laboratory, if available: __________________________________________________________________________ Issuer verification status / date / evidence: ______________________________ Permission or distribution basis for sharing this report, if required: __________________________________________________________________________ Unresolved spelling, lot, date or version differences: _____________________ __________________________________________________________________________ A matching product name or local filename does not link another client's report to your order. Retain the original issuer, named client, identifiers, dates and results; keep any supplier explanation on a separate cover sheet. Clarify differences in formulation, nominal amount or reported content with the issuer and supplier before using the report for a procurement decision. Review state: [ ] scope documented [ ] clarification needed [ ] mismatch [ ] test not performed [ ] not reported [ ] not applicable, with reason Reason / follow-up question: ______________________________________________ 2. KEEP IDENTITY, PURITY AND CONTENT SEPARATE Identity asks which material the stated analysis supports. HPLC purity is a method-specific chromatographic result, often expressed as peak area. Peptide content or assay concerns a stated amount or fraction of peptide under its own measurement basis. HPLC area percentage alone is not the peptide amount per vial, net peptide content or complete identity evidence. A. Identity Identity test named in the report, if any: _________________________________ Reported result and reference / expected value: ___________________________ __________________________________________________________________________ Method and report page / evidence reference: _______________________________ Written requirement and whether this result addresses it: _________________ __________________________________________________________________________ State: [ ] documented [ ] test not performed [ ] not reported [ ] mismatch [ ] not required, reason: _______________________________ B. HPLC / chromatographic purity Method reference / conditions reported: ___________________________________ Detector or wavelength, if stated: ________________________________________ Reported result, unit and basis (for example, area %): _____________________ Chromatogram / integration record reference, if supplied: __________________ __________________________________________________________________________ Written purity criterion and method basis: ________________________________ Are the result and criterion on a comparable basis? ________________________ Unresolved peaks, method differences or absent information: ________________ __________________________________________________________________________ State: [ ] documented [ ] test not performed [ ] not reported [ ] mismatch [ ] not required, reason: _______________________________ C. Peptide content / assay / amount per vial Measurement requested and why: ____________________________________________ Reported content or assay result, units and measurement basis: _____________ __________________________________________________________________________ Method reference / report page: ___________________________________________ Amount per vial stated on the label or quote: _____________________________ Independent content measurement available? ________________________________ Written content requirement and supporting evidence: ______________________ __________________________________________________________________________ State: [ ] documented [ ] test not performed [ ] not reported [ ] mismatch [ ] not required, reason: _______________________________ Other project-specific analytical requirements, if agreed: Field / method / result / unit / criterion / report reference: _____________ __________________________________________________________________________ __________________________________________________________________________ 3. MATCH EACH RESULT TO A WRITTEN REQUIREMENT Duplicate this record for each required analytical field. Field under review: _______________________________________________________ Written requirement and agreement reference: ______________________________ Reported result / unit / method: __________________________________________ Applicable lot and report page: ___________________________________________ Review outcome: [ ] reported result meets the stated criterion [ ] reported result differs from the stated criterion [ ] insufficient evidence to compare [ ] not applicable, with written reason Reason and unresolved scope: ______________________________________________ __________________________________________________________________________ Do not use this comparison to make a broader quality claim than the report supports. A sample or historical report can explain document format but does not establish the status of a new order batch. Third-party COA and HPLC files are confirmed by item and project, not assumed to exist for every request. 4. INDEPENDENT TESTING AND FOLLOW-UP Additional testing required? ______________________________________________ Agreed sample / batch linkage: ____________________________________________ Laboratory / method / acceptance criterion: ________________________________ __________________________________________________________________________ Written agreement reference and date, before payment: ______________________ Initial test and retest cost responsibilities: ____________________________ Result-review and notification responsibility: ____________________________ Agreed remedy if the sample fails written criteria: _______________________ __________________________________________________________________________ If the written project record includes a remedy for a BioPepSyn Lab bulk order, record the agreed option here (for example, refund or replacement production batch) and the party responsible for any retest cost. Do not assume a remedy, refund, replacement or cost allocation from this worksheet; confirm the sample, laboratory, scope, criteria, remedy and cost allocation in writing before payment. 5. DOCUMENT-REVIEW OUTCOME [ ] Relevant records collected for the next procurement review [ ] Current-batch linkage still needs confirmation [ ] Analytical scope or result needs clarification [ ] Difference against the written specification needs resolution Open questions / responsible party / follow-up date: _______________________ __________________________________________________________________________ Quote, report version and correspondence retained at: _____________________ __________________________________________________________________________ CONTACT AND USE SCOPE BioPepSyn Lab | Worldwide B2B research peptide supply WhatsApp: https://wa.me/biopepsynlab Email: info@biopepsynlab.com Ask for the applicable file using the product, report or lot reference.
