Bridge Labs
Independent analytical laboratory
Purity & identity testing
for peptides. Verifiable by code.
We measure the purity, identity and safety of the sample you send us and publish genuine, code-verifiable results. We do not sell what we test. Already have a report’s code? Confirm it is authentic and open the original certificate.
Calibrated instruments · from $100 per sample.
What we test
A full analytical picture of a sample
Purity, identity and safety, each measured by an appropriate method and reported against a clear specification.
HPLC purity
How much of the sample is the intended compound, and what else is present, by reversed-phase HPLC.
Learn more →Identity (MS)
Confirmation by mass spectrometry that the molecule is the one named on the label.
Learn more →Endotoxin (LAL)
Bacterial endotoxin load reported in EU/mg, a distinct safety question for parenteral material.
Learn more →Sterility & microbiology
Whether a sample carries viable bacteria or fungi, and how heavy any microbial load is.
Learn more →Heavy metals
Elemental impurity screening by ICP-MS: which metals are present, and at what level.

Analytical methods
The instruments behind each figure
Validated methods on calibrated instrumentation, with reference standards and controls run alongside every batch.
- RP-HPLC · UV / PDA
- Purity and impurity profiling: what proportion of the sample is the target compound.
- LC-MS / MS · ESI
- Identity by molecular mass: confirmation the molecule is the one named.
- LAL · kinetic chromogenic
- Bacterial endotoxin load in EU/mg, a distinct safety check for injectables.
- ICP-MS · elemental
- Heavy metals: arsenic, cadmium, lead, mercury and catalyst residues.

Why it matters
Independent by design
A result means more when the party reporting it has nothing to gain from the outcome. We do not sell the substances we test, and we are not tied to any vendor. Every figure comes from an actual analysis of an actual sample, never an estimate, a flattering round number, or an old report reused for a new batch.
Methods are validated and run on calibrated instrumentation, with reference standards and controls alongside every batch. Questions about a report or our procedures? Contact us.
- Genuine reports only. Never a certificate for a sample that wasn’t tested.
- Tamper-evident. Each report carries a SHA-256 integrity hash.
- Confidential. Your details are never published next to a report.
