Know what is actually
in the vial.
HPLC purity and LC-MS identity testing for research-use-only peptides, reported in 3–5 business days with a certificate your customers can verify themselves. No vendor affiliations, no conflicts of interest. Based in Nassau, The Bahamas.

RP-HPLC / UV 214 nm
Representative purity trace
Illustrative trace. Every certificate Summit issues carries the real chromatogram for that specific sample.

Enter the COA number and the access code printed on the certificate. No account required.
Testing services
A complete analytical picture of your material
Order tests individually or as a panel. Every result is reported against a stated specification, so a certificate tells you whether the material passed — not just what the instrument read.
HPLC Purity
RP-HPLC / UV
Reversed-phase separation with UV detection. Reports area-percent purity and the full impurity profile, with the chromatogram attached to the certificate.
LC-MS Identity
LC-MS (ESI)
Electrospray mass spectrometry confirming the molecular weight of the compound actually present in the vial.
Net Peptide Content
HPLC vs. certified reference standard, corrected for water and counterion
Measures how many milligrams of actual peptide are in the vial — not how many milligrams of powder are in the vial.
Nasal Spray Testing
RP-HPLC / UV + LC-MS, delivered-dose assay
Full analysis of peptide nasal sprays: what is in the bottle, what actually leaves the nozzle, and whether it has degraded in solution.
Capsule Testing
Extraction + RP-HPLC / UV, LC-MS identity
Measures how much active is in each capsule and how consistently it is distributed across the batch.
Fentanyl Screen
LC-MS/MS
Screens submitted material for fentanyl and common fentanyl analogs. Reported as detected or not detected against a stated limit of detection.
Bacterial Endotoxin
Kinetic chromogenic LAL, USP <85>
Kinetic chromogenic LAL testing per USP <85>, reported in endotoxin units.
Sterility Screen
PCR-based rapid sterility (compendial USP <71> on request)
Rapid nucleic-acid sterility screening for lyophilized and reconstituted material — a release-grade answer in days, not weeks.
Lot Conformity (Multi-Vial)
Three vials assayed independently, mean and standard deviation reported
Tests three vials from the same lot instead of one, and publishes the spread — evidence the batch is uniform, not just that one vial passed.
Blend Composition
RP-HPLC / UV against per-component reference standards, LC-MS identity
For multi-peptide blends: confirms every declared component is present, and in the ratio the label claims.
Heavy Metals
ICP-MS
Elemental impurity screening for arsenic, cadmium, chromium, mercury, and lead by ICP-MS.
Residual Solvents
SoonHeadspace GC-MS
Detects acetonitrile, TFA-related residues, and other synthesis solvents carried through purification.
Water Content
SoonKarl Fischer titration
Moisture content in lyophilized powder — the hidden variable behind mass-balance discrepancies.
Stability Program
Timepoint testing under controlled storage, ICH Q1A principles
Enrolled testing that answers what a purity number never can: how the material holds up over time, in the conditions it will actually be stored in.
How it works
Sample to published certificate
Register and ship
Tell us what you are submitting and we issue an accession number and shipping instructions the same business day. One vial covers most chemistry panels; nasal sprays and capsules need a little more, and we tell you how much up front.
Analysis
Samples are logged on receipt and run on calibrated instrumentation against reference standards. Every run carries system suitability checks and a documented chain of custody.
Certificate issued
You receive a certificate with results, specifications, the labeled chromatogram, and an access code. Pass the code to your customers and they can verify the batch against our records themselves.
Why Summit
A test result is only worth the independence behind it
Purity and identity, always together
HPLC tells you how much of one compound is in the vial. LC-MS tells you whether that compound is what the label claims. We do not issue one without the other, because a purity number alone is an incomplete answer.
Every certificate is independently verifiable
Each COA carries a number and an access code printed on the certificate itself. Hand both to a customer and they can confirm the batch against our records — no account, no request form, no taking your word for it. Our database is not browsable, so verifying your certificate never exposes anyone else’s.
3–5 business day standard turnaround
Standard chemistry results are reported within 3–5 business days of sample receipt. Your COA is ready before the batch ships, not two weeks after your customers started asking questions.
Structurally independent
Summit does not manufacture peptides, resell them, or hold equity in anyone who does. We have no incentive to make a result look better than it is — which is the entire reason a third-party number means anything.
Adulteration screening, not just purity
Purity tells you what the material is; it does not tell you what else came with it. We screen for fentanyl and common analogs by targeted LC-MS/MS and report the result against a stated limit of detection — a question a purity number structurally cannot answer.
The full chromatogram, not just a number
Every purity certificate includes the labeled chromatogram, retention times, and each impurity peak above the reporting threshold. If a batch has a problem, you will see exactly where it is.
Failing results are issued the same way
If a sample does not meet spec, the certificate says so plainly and the result stands in our records exactly as found. Clients cannot have a number revised, softened, or withdrawn after seeing it. A lab that edits results to order is not producing independent data.
