How we test
We test nootropic compounds by HPLC-MS with accurate-mass confirmation. In a blend, each component is identified on its own, so the certificate shows what is actually in the sample.
We can measure the amount of each compound where a reference standard is available.
What we measure
| Identity | HPLC-MS accurate mass |
|---|---|
| Purity | HPLC-UV or HPLC-MS |
| Content | External-standard quantitation where a reference is available |
| Blends | Each component identified and reported |
What is on the certificate
- List of components with identity result
- Purity and, if requested, amount of each component
- Chromatogram and spectrum
- Method, date and Certificate Number
What to send
- Powder, capsule, tablet or solution in a sealed container
- Stated composition and amounts
- Batch or lot number
Please wait for our packing instructions before you ship. They confirm amounts, container, temperature and where to send the samples.
