Abstract

Et kalibrert spektrometer kan Indirekte bestemme en fysisk eller kjemisk egenskap ved en prøve basert på spektrale reaksjoner målt med spektrometeret når det gjelder denne bestemte prøve. Oppfinnelsen tar sikte på en fremgangsmåte til kalibrering eller omkallbrerlng av et andre spektrometer i lys av det første spektrometer eller kalibrering av dette. Kalibreringen gjør bruk av et unikt valg og manipulering av spektrale data som, fåes fra både det første og det andre instrument. Omkallbrerlng gjør bruk av et unikt valg og manipulering av spektrale data fra det samme første instrument , som fremkommer både før og etter behovet for omkallbrerlng oppstår. 1 stedet for å modifisere de respektive reaksjoner ved det første instrument og det andre instrument eller det første instrument før og etter behovet for kalibrering oppstår, vil denne oppfinnelse modifisere kalibreringsligningen for det andre instrument eller omkalibrerte Instrument for å frembringe overensstemmende resultater med de som fremkom med det første instrument eller det første instrument før det mister sin kalibrering. En kali-breringsllgnlng er en ligning som omformer spektrale data for en bestemt prøve ved flere forskjellige bølgelengder til en beregnet verdi for en kjemisk eller fysisk egenskap. Generelt er formen på slike kali-brer ingsligninger den som finnes ved en lineær kombinasjon av absorbanser eller matematiske transfor-mer av absorbanse målt med det første og det andre instrument for hver prøve. Overraskende, og bekreftet statistisk, blir nøyaktigheten ved det kalibrerte eller omkalibrerte instrument opprettholdt og i noen tilfeller forbedret.
