Trust comes from proof,
not claims.
Purity by HPLC. Identity by LC-MS. An independent lab analysis for every batch. Here is exactly how each reference material is verified before it reaches your lab.

01How every batch is verified
Three checks, documented — before it ships.
High-performance liquid chromatography
Each batch is separated by HPLC to quantify purity. A single dominant peak with a clean baseline confirms the reference material is ≥99% pure — the tall peak you see is the compound; the flat baseline is the absence of impurities.
- ≥99% purity threshold
- Per-batch — never inferred
- Retention time recorded
LC-MS mass confirmation
Liquid chromatography–mass spectrometry confirms the molecule is what the label says. The measured mass is matched against the expected molecular weight, verifying identity beyond purity alone.
- Molecular-weight match
- Identity, not just purity
- Documented per batch
Independent batch lab analysis
Every vial carries a batch number that maps to its independent batch analysis (Janoshik). The analysis records purity, identity and test dates for that exact batch — published on our Lab analyses page.
- Traceable batch number
- Published on Lab analyses
- Matches the vial
02Documentation
An independent analysis for every batch.
Not a generic spec sheet — a batch-specific record. The batch number on the vial maps to its published analysis, so purity and identity are traceable to the exact batch.
And it isn't just our word: every batch is tested by Janoshik Analytical, an independent laboratory, on purity, endotoxins and heavy metals — with reports you can verify at the source.
