K\u00e4ytt\u00f6\u00f6noton ensimm\u00e4isess\u00e4 vaiheessa suoritettiin laitteelle aiemmin suunnitellut suorituskykytestit, ja toisessa vaiheessa kehitettiin mittausmenetelm\u00e4t 27 alkuaineelle. Kirjallisessa osassa k\u00e4siteltiin ICP-MS:n (Inductively Coupled Plasma-Mass Spectrometry, induktiivisesti kytketty plasma-massaspektrometri) teoriaa yks\u00f6is- ja kolmoiskvadrupoliteknologioissa, mittauksissa esiintyvi\u00e4 h\u00e4iri\u00f6it\u00e4 ja niiden poistoa, analyyttisen kemian mittausep\u00e4varmuutta sek\u00e4 teollisuuden sovelluksia ja haasteita.\n\nSuorituskykytesteiss\u00e4 arvioitiin uuden laitteen stabiilisuutta, mittaustulosten oikeellisuutta, spektraalisten h\u00e4iri\u00f6iden poistoa, kontaminaatiota, mittausherkkyytt\u00e4 ja resoluutiota. Testeille m\u00e4\u00e4ritellyt l\u00e4p\u00e4isykriteerit oli t\u00e4ytett\u00e4v\u00e4, jotta laite voitaisiin ottaa teollisuuslaboratorion rutiinik\u00e4ytt\u00f6\u00f6n.

Kiinnostuksen kohteena oli etenkin seleeni, jonka mitattavuus ei ole aiemmin ollut halutulla tasolla. My\u00f6s muille ep\u00e4puhtauksille luotiin mittausmenetelm\u00e4t. Suorituskykytesteiss\u00e4 ja menetelm\u00e4nkehityksess\u00e4 k\u00e4ytettiin referenssimateriaaleja IARM-189A, IARM-190A ja IARM-191A sek\u00e4 teollisuuden tuotantoprosessiliuoksia.\n\nL\u00e4hes kaikki suorituskykytestit t\u00e4yttiv\u00e4t asetetut kriteerit.
