ACS Peptide Testing Labs is the independent lab researchers trust for defensible peptide purity testing. Every method in our peptide testing labs is validated to ICH and USP guidelines and run by PhD analytical chemists. Choosing independent peptide testing labs means every certificate of analysis is traceable, reproducible, and audit-ready — the standard compounding pharmacies, research institutions, and pharma clients require.
State-of-the-art HPLC, LC-MS, and mass spectrometry systems for precise peptide characterization
Standard testing completed within 9-11 business days.
Our team includes experienced biochemists and analytical chemists specializing in peptide research and testing
Detailed certificates of analysis with complete data interpretation and methodology documentation
Peptide purity testing answers one question: how much of the material in the vial is the declared peptide. A complete panel from an independent peptide testing lab pairs that purity number with an identity confirmation, because a sample can be 99% pure and still be the wrong compound. Here is what each method contributes and what a defensible Certificate of Analysis should state.
Reverse-phase HPLC with UV/DAD detection at 214 nm separates the target peptide from truncated sequences, deletion impurities, and residual reagents. Purity is reported as area percent. The report should name the column chemistry, the gradient, the detection wavelength, and the reporting limit — a bare percentage is not verifiable.
LC-MS compares the measured molecular weight against the theoretical monoisotopic mass of the declared sequence. This is the only step that confirms identity; retention time alone can be matched by a similar peptide.
ICP-MS for heavy metals, GC-MS for residual solvents, and LAL for bacterial endotoxin. These matter most for injectable-grade research material, where a clean purity result says nothing about what else came along in the synthesis.
Karl Fischer titration establishes water content so peptide content per vial can be calculated accurately. ICH Q1A stability programs track how purity moves across real-time and accelerated pull points.
ACS runs each of these in a single lab in Sun City Center, Florida, using validated methods aligned to ICH and USP guidance, and returns a signed COA in 9-11 business days.

Common questions about our peptide analysis and verification services
We test all types of research peptides including synthetic peptides, natural peptides, modified peptides, cyclic peptides, and peptide conjugates. Our analytical methods are suitable for peptides ranging from dipeptides to large polypeptides.
Standard peptide testing typically takes 9-11 business days from sample receipt. Complex testing panels or custom protocols may require additional time.
Our peptide testing laboratory utilizes High-Performance Liquid Chromatography (HPLC), Liquid Chromatography-Mass Spectrometry (LC-MS), ESI-MS, and other advanced analytical techniques to ensure accurate peptide characterization and purity determination.
Minimum sample requirements vary by test type. For basic purity testing, we typically need 1-5mg of peptide. For comprehensive analysis including molecular weight verification and contaminant testing, we recommend 5-10mg. Contact us for specific requirements for your peptide testing needs.
Our Certificate of Analysis includes peptide purity percentage, molecular weight confirmation, HPLC chromatogram, mass spectrometry data, identification of impurities, testing methodology details, and expert interpretation. All reports are reviewed and signed by our PhD-level scientists.
Yes, we provide GMP-compliant peptide testing services suitable for regulatory submissions. Our testing protocols follow FDA guidelines and ICH standards for pharmaceutical peptide analysis. We can customize testing to meet specific regulatory requirements for your peptide products.
Peptide samples should be shipped frozen with dry ice or at room temperature for stable peptides. We provide detailed shipping instructions and accept samples via FedEx, UPS, or other major carriers. For temperature-sensitive peptides, overnight shipping with appropriate cold packs or dry ice is recommended.
