Independent third-party results you can trust — validated methods, modern instrumentation, and scientific integrity.
Our flagship service. Reversed-phase HPLC with UV detection determines peptide purity as a percentage and identifies impurities, while LC-MS with high-resolution accurate mass confirms the peptide's identity by comparing observed molecular weight to the expected value. Both tests are performed on the same sample and delivered on a single Certificate of Analysis.
Quantifies the actual active peptide weight in your sample by accounting for water, salts, counterions, and other non-peptide components. Essential for accurate dosing and formulation when the label weight alone is not enough.
Verify that multiple vials from the same batch are consistent. Each vial you submit is tested independently and the report shows how closely the units conform — quantifying vial-to-vial variance so you know your batch is uniform, not just that one vial passed.
Specialty add-on for human growth hormone samples. Size Exclusion Chromatography (SEC-HPLC) quantifies the percentage of dimer (two HGH molecules bound together) and higher molecular weight aggregates. Dimer is technically HGH but does not appear in standard purity tests and reduces bioactivity, so a dedicated analysis is required to detect it.
Every analysis at Sonic Laboratories follows rigorously validated methods. As an independent third-party lab, our results are unbiased and reproducible. From sample receipt to final report, each step is documented and reviewed to ensure scientific integrity and give you confidence in the data.
