Batch evidence
Quality evidence that keeps specification and result separate.
A complete quality review connects molecular identity, analytical method, specification, result, issuer, and batch provenance in one traceable document package.
Request the applicable document indexSpecification, method, result, manufacturing site, document status, and target-market suitability are confirmed per product and batch.
Inside the instrument room
Instruments, samples, and operator handling.
Field photographs connect the liquid chromatography workstation, autosampler, and sample handling. Method suitability and results are reviewed against the applicable sample and analytical records.
CoA and analytical support
Use batch documents for the sourcing decision.
≥99%Portfolio specification by HPLC
The public portfolio specification is ≥99% by product-appropriate HPLC. The applicable sample identity, method, batch result, issuer, and CoA govern every sourcing decision.
- Original files retain issuer, sample alias, and batch provenance
- Identity review by LC-MS where applicable
- Purity review by product-appropriate RP-HPLC or UPLC
Quality review index
Build a complete quality package from traceable records.
The quality route connects product identity, analytical method, specification, result, and source provenance, then organizes the applicable records for technical and procurement review.
- 01Identity recordLC-MS · ID · Project-specificReview focusConfirm molecular identity
Source file, sample alias, method, and instrument context remain attached to the review.
- 02Purity recordRP-HPLC / UPLC · Project-specificReview focusSeparate specification from result
Method, wavelength, column, integration, and related-peak context are reviewed together.
- 03Composition recordApplicable assay · Project-specificReview focusCharacterize supplied material
Water, residual solvents, counter-ion, and peptide content are aligned to the actual material form.
- 04Batch recordCoA · supporting records · Project-specificReview focusConnect evidence to the offer
Product, batch, responsible site, release status, and disclosure rights govern the document set.
Source document library
Review the original CoA and chromatographic records with their product, lot, method, and report context intact.
Each source record retains its original issuer, sample, method, lot, date, result, laboratory, and operator fields. Main-peak area and peptide content are presented as distinct analytical measures; current supply decisions use the applicable batch CoA.
Document pathway
Move the right documents through each project stage.
Documents are organized by product, batch, manufacturing site, project stage, target market, and confidentiality level, creating a clear path from initial scope to the final decision record.
- 01
Initial scope
Public identity, portfolio specification, and available document categories.
- 02
Qualification
Company, intended use, target market, product, batch, and responsible-site review.
- 03
NDA review
Controlled technical, quality, traceability, and manufacturing information where applicable.
- 04
Decision record
Approved specification, CoA, method context, packaging, release, and supply records for the proposed offer.
Decision framework
Core quality attributes in sourcing review
Method families connect each quality attribute to the analytical decision it supports; the applicable product specification and batch CoA complete the record.
| Quality attribute | Applicable method family | Decision supported |
|---|---|---|
| Identity | LC-MS or intact mass where applicable | Confirm the peptide and modification state |
| Purity | Product-appropriate RP-HPLC or UPLC | Report the main component and related peptides |
| Composition | Water, counter-ion, residual solvents, peptide content | Characterize the supplied material |
| Batch record | Specification, CoA, methods, and supporting records | Support product- and batch-specific review |
