Analytical Testing & Quality Control
Comprehensive analytical support for peptide raw materials and finished research-grade peptides. Our testing workflows are aligned with ISO/IEC 17025 and CMA requirements, so the numbers in your COA can stand up to technical review.
Core testing panel
Six core assays cover identity, purity and safety for peptides and raw materials, with documentation to match.
HPLC purity assay (95% – >99%)
Main peak purity by RP-HPLC with UV detection at 214 nm.
MS / ESI mass spectrometry identity
Molecular weight confirmation against the expected sequence.
NMR structural confirmation
Available on request for structural verification.
Moisture content by Karl Fischer
Residual water determination for lyophilised material.
Endotoxin (LAL) and sterility
Performed where the research protocol requires it.
Shipping documents
COA and MSDS standard; HPLC and MS spectra on request.

Sample, reporting and accreditation
Sample requirement
20 mg lyophilized powder or 1 mL solution per test; special tests confirmed case by case.
Reporting
Every report includes the method, the raw chromatogram or spectrum, and a pass/fail conclusion. COA and MSDS available on request.
Accreditation
ISO/IEC 17025 (CNAS, ILAC-MRA) and CMA accredited — results recognised by member bodies internationally.
Documents and deliverables
Issued against a specific batch, so the record is usable by your QA team.
- COA with method and pass/fail conclusion
- Raw HPLC chromatogram or MS spectrum
- MSDS on request
- Batch-linked traceability
