The 6 Quality Checkpoints
What do we actually check?
Quality is more than a purity number. Our quality verification looks at six important checkpoints.
Checkpoint 01
Identity
Before anything else, we confirm the material is genuinely the compound it claims to be. Mass spectrometry reads the molecular fingerprint and matches it against the expected structure.
MethodMass Spectrometry (MS)
Why It Matters
If identity isn't confirmed first, every other number on a report is meaningless. Identity is the foundation of trust.
