The Food and Drug Administration (FDA), Office of Regulatory Testing and Surveillance (ORTS), Arkansas Human and Animal Food Laboratory (ARHAFL) Chemotherapeutic workgroup is the primary laboratory for the chloramphenicol and nitrofurans in aquaculture species shrimp, frog, crab, crawfish, mussel, barramundi, croaker, and cobia. The laboratory analyzes more than six thousand (6000) subsamples each year. The automated solid phase extraction system (ASPEC) HLB cartridges are consumables used on the Gilson GX-274 system at Arkansas Laboratory (ARHAFL). The ARHAFL Chemotherapeutic workgroup is the servicing laboratory for the FDA’s antibiotics in aquaculture program. ARHAFL needs seven thousand (7,000) cartridges for the program’s routine sample analyses. The cartridges must be validated to use them on regulatory samples.
