Cold chain
Purity is a chain, not a checkpoint.
A certificate describes the material at release. Everything after release is logistics — and logistics is where most suppliers quietly lose the number they printed.
01Release
Lot passes assay and is sealed under an inert headspace. The COA is published to the register the same day.
02Cold store
Held at 2–8°C in monitored storage. Excursions are logged against the lot, not the shipment.
03Insulated dispatch
Packed with phase-change coolant and a temperature indicator, then moved on an expedited service.
04Verified arrival
Check the indicator against the lot. If it tripped, it is replaced or refunded — no return required.
