T\u00e4rkein laite uuteaineiden erotteluun ja tunnistamiseen on GC-MS, jolle on olemassa yliopistojen kokoamia valmiita kirjastoja ja kaupallisia kirjastoja, kuten NIST-kirjastot (National Institute of Standards and Technology).

Ennen uuteainetunnistuksia uutteet eristet\u00e4\u00e4n uuttolaitteella, kuten Soxtecilla tai ASE:lla. \nKokeellisessa osassa vertaillaan Soxtec- ja ASE-uuttolaitteita. Tarkoituksena oli selvitt\u00e4\u00e4 ASE:n soveltuvuus analyysilaboratorioon Soxtecin rinnalle gravimetriseen m\u00e4\u00e4ritykseen. Erilaisilla testeill\u00e4 selvitettiin, kuinka uuttotulokset olivat vertailtavissa laitteiden v\u00e4lill\u00e4. ASE:lla rinnakkaisista uutoista saatiin hyv\u00e4t tulokset punnituksissa, mutta Soxtec-uuttoihin verrattuna tulokset sijoittuivat valvontakortin alarajoihin. Tulosten perusteella analyysilaboratorioon voitaisiin hankkia ASE, jolla voidaan lis\u00e4t\u00e4 laboratorion kapasiteettia uuteainem\u00e4\u00e4rityksiss\u00e4.\nUuteainekartoitus aloitettiin n\u00e4ytteenottokierroksilla sellutehtaalla.
