๐Ÿ“‹ What is a COA?

A Certificate of Analysis (COA) is an official quality document issued by an accredited analytical laboratory. It confirms that a product meets defined specifications for identity, purity, potency, and safety. Each COA is batch-specific and traceable.

๐Ÿ† Our Standards
  • HPLC purity โ‰ฅ 99.0% per component
  • MS/MS bond integrity per amino acid
  • Endotoxin < 0.10 EU/mg (LAL method)
  • Sterility: no growth at 14 days
  • 100% vials UV-inspected
  • Robotic aluminium crimp sealing
  • ISO Class 5 closed-vacuum filling

๐Ÿญ Our Manufacturing & Quality Control Process

Every vial goes through a strict 7-stage production and quality chain. Nothing leaves our facility until every checkpoint is confirmed.

1
๐Ÿงช Vial Preparation & Sterilisation
All glass vials undergo a full triple-wash cycle using endotoxin-free USP Water for Injection (WFI). Vials are then depyrogenated at 250 ยฐC for a minimum of 30 minutes to eliminate any pyrogens or biological residue. Each vial is individually tested for particulate matter and surface contamination before entering the filling line. No vial enters production unless it meets a zero-contamination baseline.
2
๐Ÿ”ฌ Peptide Synthesis & Pre-Release QC
Each peptide is synthesised via Solid Phase Peptide Synthesis (SPPS) using Fmoc/tBu orthogonal protecting group chemistry on a validated automated synthesiser. Upon completion of synthesis, the raw peptide bulk undergoes mandatory HPLC purity testing and ESI mass spectrometry to confirm molecular identity and amino acid bond integrity before advancing to any downstream steps. Batches failing to meet โ‰ฅ 99.0% HPLC purity are rejected and destroyed.
3
โ„๏ธ Lyophilisation (Freeze-Drying)
The purified peptide solution is snap-frozen at โˆ’80 ยฐC using liquid nitrogen-assisted cooling to preserve structural integrity and prevent degradation. Primary drying removes bulk water under controlled vacuum at โˆ’40 ยฐC / 100 mTorr. Secondary drying at +25 ยฐC / 50 mTorr removes residual bound water to achieve a final moisture content below 5.0% (Karl Fischer confirmed). Lyophilisation locks the peptide in its most stable state, maximising shelf life and reconstitution reliability.
4
๐Ÿญ ISO Class 5 Closed-Vacuum Filling Room
All filling operations are conducted inside an ISO Class 5 (EU GMP Grade A) cleanroom maintained under continuous positive nitrogen pressure. The environment is HEPA-filtered to โ‰ค 3,520 particles โ‰ฅ 0.5 ฮผm per cubic metre. Vials are filled under a closed vacuum to prevent any atmospheric contact with the lyophilised product. Operators are fully gowned; no bare skin contact with vials or product at any stage. The room is sterility-tested on a continuous environmental monitoring schedule before and after each production run.
5
๐Ÿค– Robotic Aluminium Crimp Sealing
Once filled, vials are immediately transferred โ€” without human contact โ€” to an automated robotic sealing station. Each vial receives a bromobutyl rubber stopper and an aluminium overseal applied by a calibrated servo-crimping head. Crimp torque is verified electronically on 100% of units to ยฑ0.05 Nยทm precision. A dye ingress challenge test is periodically conducted on sealing performance samples to confirm hermetic integrity under elevated atmospheric pressure conditions.
6
๐Ÿ”ฆ 100% UV & Visual Contamination Inspection
Every single vial โ€” without exception โ€” is individually inspected under a 365 nm UV-A illumination chamber. UV light causes any microbial contamination, proteins, or fluorescent compounds to emit visible fluorescence, allowing immediate rejection of affected units. Vials also pass through white and black background visual inspection stations for particulate matter detection and seal assessment. Any vial displaying fluorescence, visible particles, discolouration, or seal anomaly is permanently quarantined and destroyed.
7
โœ… Final Release Testing & COA Issuance
A statistically representative sample from each completed batch is submitted to final release testing: endotoxin (LAL chromogenic), sterility (USP <71> membrane filtration, 14-day incubation), particulate matter (USP <788> light obscuration), and a final HPLC purity re-confirmation. The Certificate of Analysis is issued only upon full numerical pass of every specification. Batch records are archived for a minimum of 5 years and are traceable to each individual lot number printed on the vial label.
