HALO supplies batch-specific analytical documentation for qualified laboratory purchasers. Every active lot is tied to a certificate of analysis (COA) covering HPLC purity, identity confirmation, lot number, and test date. The COA ships with every order. Product pages summarize documentation standards (purity, identity, RUO); the full certificate is included with shipment and available on request with your SKU and lot number.
What each COA includes
- Compound name and SKU / vial size
- Lot / batch number
- Test date and analytical method (HPLC, LC-MS/MS where applicable)
- Purity percentage and identity pass/fail
- Certificate of analysis included with shipment
How to verify a lot
Match the lot number on your vial label to the COA included with your shipment. Product pages show a current-lot documentation summary; for a digital copy after delivery, email support with your SKU and lot number. For procurement files, retain the COA with your purchase order and receiving log.
