Overview
Our Purity & Quantity panel delivers chromatographic evidence of peptide identity, impurity profile, and mass-on-hand using a controlled HPLC workflow on the Agilent 1260 Infinity platform. Results are formatted for internal release review and COA attachment—ideal when you need defensible numbers before formulation, batch release, or third-party verification.
- HPLC (1260 Infinity)
- Purity assessment
- Quantity assessment
- 1 vial per submission
Method
Chromatographic separation
Reverse-phase HPLC with UV detection at 214 nm and 280 nm, calibrated against qualified reference standards.
Purity reporting
Main peak area percent reported with chromatogram trace suitable for audit review.
Quantity reporting
Mass estimated from peak response relative to submission weight or declared concentration when provided.
Specimen
- One clearly labeled vial per compound submitted for this panel.
- Minimum 1 mg peptide material recommended for robust quantitation.
- Lyophilized powder or liquid; note solvent and concentration on the label.
- Ship cold when stability requires; include order barcode inside the package.
Reporting
- Certificate of analysis (PDF)
- Chromatogram trace image
- Method reference and run conditions
- Analyst notes for out-of-spec flags
FAQ
- Can I combine this panel with sterility or endotoxins?
- Yes. Sterility and endotoxins can share one vial when ordered together. Purity & Quantity always requires its own dedicated vial.
- What if my sample is a complex mixture?
- Submit with as much identity and solvent information as possible. Complex matrices may require a feasibility review before intake.
