How every Lyze Labs batch is verified
Every Lyze Labs batch is verified twice. Our own quality control laboratory tests it by HPLC for purity and mass spectrometry for identity and decides release, and an independent third-party laboratory confirms the result before anything ships. Both results go onto the Certificate of Analysis, published online and matched to the lot number printed on the vial. Manufacturing runs to GMP, the quality system to ISO 9001, and confirmatory analysis at an ISO/IEC 17025 accredited laboratory. Verified compounds are held to a 99 percent-plus purity standard. Everything is supplied strictly for laboratory research use.
The verification process
Every batch is sampled
Each production batch is sampled before it is released to the catalog. Verification is done per batch, not once per product, so a compound's status reflects the exact lot in circulation.
Independent third-party HPLC and mass spec
Every batch is analysed twice. Our own quality control laboratory runs high-performance liquid chromatography for purity and mass spectrometry for identity, and decides release. An independent laboratory (Janoshik Analytical) then confirms the result with no commercial interest in the outcome. The batch is never released on our own analysis alone, which is what makes the number verifiable.
The Certificate of Analysis is published online
The full chromatogram and the numeric purity result are published on the lab-results page and tied to the batch lot number. The certificate lives online so anyone can check it before and after ordering.
The vial lot matches the certificate
The lot number printed on the vial you receive matches the batch certificate published online. That match is the verification step: a certificate only means something if you can tie it to the vial in your hand.
Two laboratories, not one
Every batch is released by our own quality control laboratory and confirmed by an independent one. In-house testing alone is a self-assessment. Third-party testing alone says nothing about the controls behind the batch. Published together, they answer the question a buyer is actually asking.
Lyze Labs Quality Control
Analyses every batch on arrival from synthesis and decides release against the specification set for that compound. This is the laboratory that can stop a batch.
- Reversed-phase HPLC purity
- Mass-spectrometry identity confirmation
- Karl Fischer water content
- Appearance and solution clarity
- pH determination
- Retained-sample management
Works to Good Manufacturing Practice (GMP) and ISO 9001:2015
Janoshik Analytical
Independent confirmation of purity and identity, with no commercial interest in the result. Results are posted to a public portal, so a certificate can be checked against the laboratory's own record rather than against our word for it.
- Reversed-phase HPLC purity
- LC-MS/MS identity confirmation
- Bacterial endotoxin (LAL)
Accredited third-party laboratory
Confirmatory analysis at a laboratory holding ISO/IEC 17025 accreditation, so the analytical competence behind the number is itself assessed by an accreditation body rather than asserted.
- RP-HPLC purity under an accredited method
- LC-MS/MS identity
- Bacterial endotoxin
- Elemental impurities
Works to ISO/IEC 17025:2017
Both results are published on the batch certificate. See lab results for the current set, or how testing works for the full method.
The standards behind the work
What each standard covers, and which part of the operation it applies to.
General requirements for the competence of testing and calibration laboratories. It is granted to a laboratory, not to a supplier, and it is the standard that separates a competent analytical result from an asserted one.

Where the certificate lives
The Certificate of Analysis is published on the lab-results page and matched to the batch lot number. Shipments arrive in plain, unbranded packaging with no paperwork inside; the certificate is online so it can be checked independently at any time, not a slip in the box that could be faked. Compounds still in analysis show an honest in-progress status on their product page rather than a verified claim.
What the reship guarantee covers
If a package is stopped in customs or transit and does not arrive, it is reshipped free. If material tests below its published Certificate of Analysis, it is reshipped free. Research material ships sealed and all sales are final, so the guarantee is a reship, not a cash refund. See the delivery & reship guarantee for the full terms.
The rest of the evidence
Each page answers one part of the same question. None of them asks you to take a claim on trust.

Every technique on the certificates, what it proves, and what it cannot.
Field by field, plus the red flags that tell you a certificate is worthless.
