Abstract
Fremgangsmåte for å forbedre opptak av fluidprøvedata og som omfatter utledning av optiske densitetsdata for en fluidprøve i minst to fargekanaler og minst én fluidkomponentkanal, samt bestemmelse av en fargeabsorpsjonsfunksjon ut i fra vedkommende optiske densitetsdata for fluidprøven i de minst to fargekanaler. Fremgangsmåten omfatter også beregning av en andel av den optiske densitet som forårsakes av fargeabsorpsjoner i hver av de minst ene fluidkomponentkanaler, samt fargefjerning fra de optiske densitetsdata i hver av de minst ene fluidkomponentkanaler ved å fjerne den andel av de optiske densitetsdata som forårsakes av fargeabsorpsjon.
