Quality & Testing
Every peptide we supply undergoes rigorous analytical testing to ensure research-grade purity and identity verification.
Research-Grade Quality, Guaranteed
At Amino Research, quality is not an afterthought — it is the foundation of everything we do. Our multi-stage quality control process ensures that every peptide leaving our facility meets the highest standards for purity, identity, and consistency.
We partner with accredited, independent analytical laboratories to provide transparent third-party verification. Every product is accompanied by a detailed Certificate of Analysis (CoA) that includes full chromatographic and spectrometric data.
How We Verify Quality
HPLC Analysis
High-Performance Liquid Chromatography
Our primary method for purity determination. Reverse-phase HPLC separates peptide components and quantifies purity as a percentage of the total peak area. All products must achieve ≥98% purity to pass quality control.
- C18 reverse-phase column
- UV detection at 220nm
- Gradient elution method
- Full chromatogram provided in CoA
Mass Spectrometry
LC-MS / MALDI-TOF
Mass spectrometry confirms the molecular identity of each peptide by measuring its exact molecular weight. This ensures you receive precisely the compound specified, with the correct amino acid sequence.
- Molecular weight confirmation
- Identity verification
- Impurity identification
- Mass spectrum included in CoA
Quality Control Process
End-to-end verification
Our QC process covers every stage from sourcing to dispatch. Raw materials are verified on receipt, in-process checks monitor synthesis quality, and final products undergo full analytical characterisation before release.
- Incoming material verification
- In-process quality checks
- Final release testing
- Batch tracking & documentation
