Peptide COA UK - Certificate of Analysis Verification

At Bio Peptides UK, transparency and quality are our top priorities. Every research peptide we supply comes with a comprehensive Certificate of Analysis (COA) to verify purity, composition, and quality standards.

What is a Certificate of Analysis (COA)?

A Certificate of Analysis is an official document that confirms a research peptide has been tested and meets specified quality standards. It provides detailed information about the peptide’s purity, composition, and testing methods used.

What’s Included in Our COAs

Every Bio Peptides UK product includes:

• HPLC Testing Results – High-Performance Liquid Chromatography analysis showing purity levels
• Mass Spectrometry Data – Confirms molecular weight and peptide identity
• Purity Percentage – Verified purity levels (typically ≥99%)
• Batch Number – Full traceability for every product
• Testing Date – When quality testing was performed
• Storage Recommendations – Proper handling guidelines

How to Verify Your COA

When you receive your research peptides from Bio Peptides UK, you can verify the COA by checking:

1. Batch number matches your product label
2. Purity percentage meets research standards (≥99%)
3. HPLC chromatogram shows clear, distinct peaks
4. Mass spectrometry confirms correct molecular weight
5. Testing date is recent and documented

Why COA Verification Matters

Using verified, high-purity peptides is essential for reliable research outcomes. Our comprehensive COA documentation ensures you can trust the quality of every compound you use in your laboratory work.
