Markers which are soluble in petroleum fuel and are extractable from petroleum fuel by either acidic aqueous solutions or basic solutions and develop a color in the presence of the extracting acidic or basic aqueous solution, are identified by passing a specimen putatively containing the marker through an acidic resin column or a basic resin column, as the case may be.

Marqueurs solubles dans des carburants pétroliers et extractibles à partir de ces carburants à l'aide de solutions aqueuses acides ou basiques, produisant une couleur en présence de la solution aqueuse, acide ou basique; on caractérise un marqueur en faisant passer un spécimen, censé en renfermer, à travers une colonne de résine acide ou une colonne de résine basique, selon le cas.
