CONT

La spectrométrie d'absorption est une méthode de spectroscopie électromagnétique utilisée pour déterminer la concentration et la structure d'une substance en mesurant l'intensité du rayonnement électromagnétique qu'elle absorbe à des longueurs d'onde différentes. [Elle] peut être atomique ou moléculaire.
