Extrelut® NT er en specialfremstillet, inaktiv bredporet kiselgur med et højt porevolumen. Det er blevet anvendt med stor effektivitet i klinisk kemi og toksikologi til prøveklargøring af urin, blod, plasma og andre biologiske materialer. Andre anvendelsesområder omfatter miljø- og restanalyse, som f.eks. analyse af spildevand fra industri, husholdning og kloak. Extrelut® NT leveres enten som forpakkede kolonner eller som et løst sorbent. Stoffets overfladeegenskaber understøtter væske-væske ekstraktionen af lipofile forbindelser i stedet for anvendelse af en skilletragt. Når en vandig prøve tilsættes til Extrelut® NT sorbentet, fordeler prøven sig selv som en tynd film over overfladen og virker som en stationær fase. Derefter finder eluering sted ved hjælp af organiske opløsningsmidler, der ikke er blandbare med vand. Alle de lipofile stoffer ekstraheres fra det vandige ind i den organiske fase.
