Quality Control

Purity is a number you can verify, not a claim. Every ARGENT batch is analysed by an independent laboratory and released only against its certificate of analysis.

Quality Control — ARGENT

The standard

Purity ≥ 98.5%

Determined by HPLC on every production batch. Batches below threshold are not released.

Identity confirmed

Mass spectrometry confirms the compound is what the label says it is.

Independent laboratory

Testing is performed by a third party, not in-house — the result is not ours to influence.

Full traceability

Vial → carton → LOT → certificate. Each batch resolves to its own report and retest date.

How a batch is released

1
Synthesis and purificationProduced under controlled conditions with documented process parameters.
2
SamplingA representative sample is drawn from the finished batch.
3
Independent analysisAn external laboratory determines purity (HPLC) and confirms identity (MS).
4
Release decisionIf purity is below 98.5% or identity is not confirmed, the batch is rejected.
5
Certificate issuedThe COA is bound to the batch number and published to the batch lookup.

Storage and stability

Compounds are filled into amber glass, which protects light-sensitive material, and stored at 2–8 °C. Lyophilized powder carries a two-year shelf life; liquid solutions and nasal sprays carry one year, unless the label states otherwise.

Every certificate carries a retest date. We re-analyse material rather than assume it is stable indefinitely.

What we do not claim

ARGENT publishes analytical data — purity, identity, batch traceability. We make no claims about biological effect, suitability for any application in humans or animals, or therapeutic value of any compound in this catalogue.

Research Use Only. Products are intended exclusively for in vitro laboratory research purposes only. Not for human or animal consumption. Not intended to diagnose, treat, cure, or prevent any disease.
