Infrapunaspektri andmete tõlgendamiseks peab neeldumine esinema analüüdi spektri kõigis piirkondades, mis vastavad kalibreerimisstandardi võrdlusspektri nõuetele vastavatele piikidele.
Absorption shall be present in all regions of the analyte spectrum which correspond with an adequate peak in the reference spectrum of the calibration standard. A minimum of six adequate peaks is required in the infrared spectrum of the calibration standard. If there are less than six adequate peaks (7), the spectrum at issue cannot be used as a reference spectrum.
