RP-HPLC Purity Analysis
Purity is measured by HPLC-DAD. The certificate reports the main peak as a percentage of total peak area.
- Purity percentage (area % main peak)
- UV detection at research-standard wavelengths
- Vendor claim and lot screening
Flexible Testing, Uncompromising Standards.
Order any test individually or save with a bundled full panel. Regardless of whether you send one vial or fifty, the same instruments, methods, and quality controls are applied to every sample.
Because reliable data should depend on the science, not the size of the order.
Purity is measured by HPLC-DAD. The certificate reports the main peak as a percentage of total peak area.
Identity is confirmed by FTIR-ATR, CE-UV, Raman, and UV-Vis spectroscopy against reference spectra for the claimed peptide - not a purity number alone.
Elemental impurities (often called heavy metals) and bacterial endotoxins are reported with method identifiers suitable for research and vendor QA packages.
Method: Colorimetric screening for lead, arsenic, cadmium, and mercury.
Method: Kinetic chromogenic Limulus amebocyte lysate (LAL) assay for lipopolysaccharide (LPS) endotoxins from Gram-negative bacteria.
Most clients start with purity + identity, then add elemental impurities and/or endotoxin screening when supplier QA requires it.
| Assay / Package | What It Answers | Output on COA | Typical Use |
|---|---|---|---|
| Basic COA - $250 | Is it the claimed compound, and how pure? | Identity + purity % (FTIR-ATR, CE-UV, Raman, UV-Vis) | Batch QC, claim verification |
| Endotoxin Screen - $150 | Is bacterial endotoxin within limit? | EU/mg (LAL kinetic) | Contamination screening |
| Elemental Impurities - $100 | Are Pb, As, Cd, Hg elevated? | ppm via colorimetric screening | Synthesis residue / supplier QA |
| Full Panel - $500 | Identity, purity, endotoxin, and metals in one report | Combined COA + public ID | Full vendor / research documentation |
| Rush testing - $175 / vial | Need results faster than the 72-hour target? | Priority queue - 24 business hours from receipt | Add-on to any panel or test |
Yes. PacifiCOAnalytics is also written Pacific COA Analytics, Pacifico Analytics, or Pacific COA. The legal company is PACIFICOANALYTICS INC. The website is pacificoanalytics.ca.
No. PacifiCOAnalytics is an independent laboratory. We test samples you ship to us. We do not sell, manufacture, or distribute peptides or any other materials.
Identity confirmation (FTIR-ATR, CE-UV, Raman, and UV-Vis against reference spectra) and purity by HPLC-DAD. Results are issued as a certificate of analysis and can be listed on the public COA lookup.
Standard target is 72 hours from laboratory receipt. That is an estimate, not a guarantee. Rush testing (24 business hours) is available at $175 per vial.
Samples are accepted from Canada, the USA, Europe, and China. Testing is for research and quality documentation only, not for human or veterinary use.
Yes. Released certificates are posted to the public COA lookup. Anyone can check a report ID without logging in.
