Analytical standards
How we test
For qualified laboratory researchers only. Not for human or veterinary consumption.
Independent third-party analysis
Every batch is sent to KMD Analytical, an independent testing laboratory, before it is released. The laboratory has no stake in the outcome, and the report it issues is published exactly as received — nothing is re-typed, re-formatted or summarised.
Purity by HPLC
High-performance liquid chromatography separates the sample so the proportion of the target compound can be measured against everything else present. The resulting purity figure is reported as a percentage, and the release standard is ≥99% by HPLC.
Identity by LC-MS
Liquid chromatography–mass spectrometry measures the molecular mass of the material. Matching the observed mass to the expected mass confirms the identity of the compound, which purity analysis alone cannot establish.
Batch coding and traceability
Each production batch receives a unique batch code. That code appears on the vial label and on the certificate of analysis, so any vial can be matched to the exact report issued for the material it contains.
Cold-chain handling until dispatch
Material is held under controlled temperature from intake through storage, and cold-chain handling is maintained until the parcel is handed to the carrier. Lyophilized material is stable in transit.
What a certificate of analysis contains
- Sample identification and batch code
- Analytical method used (HPLC, LC-MS)
- Chromatogram traces from the run
- Purity result expressed as a percentage
- Mass confirmation against the expected molecular mass
- Laboratory signature and date of issue
Common questions
Which laboratory performs the analysis?
Analysis is performed by KMD Analytical, an independent third-party laboratory with no ownership relationship to VOW LABS. Reports are issued by the laboratory and published unedited.
What is the difference between HPLC and mass spectrometry?
High-performance liquid chromatography (HPLC) separates a sample into its components and quantifies how much of the material is the target compound, which is what a purity percentage describes. Liquid chromatography–mass spectrometry (LC-MS) measures molecular mass, which confirms that the compound present is the one named on the report.
How long are batch records kept?
Each batch carries a unique batch code that stays linked to its certificate of analysis for the life of the batch, so a vial on the bench can always be traced back to the report issued for it.
