Analytical testing, end to end
Every order includes identity and purity by HPLC and LC-MS. Extend any test with targeted add-ons for residues, contaminants, and microbial safety.
HPLC purity & content
High-performance liquid chromatography separates the sample and quantifies purity as HPLC area percent, plus the actual content per vial.
- Purity as area %
- Content (mg) per vial
- Chromatogram included
LC-MS identity
Liquid chromatography mass spectrometry confirms the compound's molecular mass, verifying you have the right molecule.
- Molecular mass match
- Identity confirmation
- Spectrum included
