An independent line in your supply chain.
Wholesalers and distributors carry the reputational cost of every incoming batch. We provide independent verification — same-batch retesting, CoA reissue, and chain-of-custody documentation — so your downstream buyers don't need to re-run the work.
Incoming QC
Independent purity and identity on inbound API from unfamiliar suppliers or new manufacturing sites.
CoA reissue
Re-analysis with a ALS-signed CoA — often required when the original manufacturer's paperwork is contested.
Batch traceability
Chain-of-custody documentation from receiving to release, retained for downstream audit.
Peptide testing
HPLC-UV and LC-MS/MS purity and identity for synthetic peptides.
ViewElemental impurity
ICP-MS panel for catalyst residues and heavy metals.
ViewMicrobiological
Bioburden and endotoxin for research materials intended for in vivo use.
ViewCustom methods
Method development for novel research compounds without published assays.
