Processos para detectar marcadores em líquidos e para marcar líquidos não polares contaminados, e, uso de agentes de deuteração.

摘要

The invention relates to a method for detecting marking materials in liquids, wherein (a) one or more, identical or different marking materials are provided in the liquid, (b) a deuteration agent is brought into contact with the liquid, and (c) the marking material is detected in the liquid by fluorescence spectroscopy. The invention further relates to a method for marking contaminated nonpolar liquids and to the use of deuteration agents for improving the detectability of marking agents in liquids.
