<p>A tracer system comprising a tracer compound for a fluid system, the tracer compound comprising one or more polyether alcohol compounds. The one or more polyether alcohol compounds is arranged for being placed in contact with a first part of said fluid system. The one or more polyether alcohol compounds is truly monodisperse. The polyether alcohol compounds comprises one or more functional groups. The one or more truly monodisperse polyether alcohol compounds is arranged for being detected in a second part of the fluid system in fluid communication with said first part of said fluid system. The tracer compound is detectable in very low concentrations.</p> |
