La méthode décrite est applicable à la détermination du benzène, du méthylbenzène (toluène), des diméthylbenzènes (xylènes) et de l'éthylbenzène (dans la suite l'abréviation BTX est utilisée) dans des échantillons homogènes d'eau et d'eau résiduaire à des concentrations supérieures à 2 µg/l. Dans des échantillons organiquement pollués, la limite de détermination peut, suivant la matrice de l'échantillon, être supérieure. Des concentrations élevées peuvent être déterminées en diluant l'échantillon. D'autres dérivés et composés apolaires présentant des propriétés physiques similaires peuvent également être déterminés par cette méthode. Il convient alors de vérifier l'applicabilité de la méthode à l'échantillon d'eau donné.
