Abstract: A method of monitoring water-soluble treatment chemicals in a fluid that is immiscible with water and which may or may not contain some aqueous fluid, the method using at least one reagent that produces an optically detectable product, the detection step can take place without separation of the aqueous phase containing the treatment chemicals from the fluid immiscible with water.

Abstract: A method for the assessment of a multiphase (aqueous and organic) sample phase, the method comprising adding at least one detection molecule to the multiphase sample; detecting a signal emitted from the detection molecule/multiphase sample mixture, the signal being detectably different when the at least one detection molecule is present in one of either an organic phase, an aqueous phase or an interface between said organic phase and said aqueous phase of the multiphase sample; and analyzing the detected signal to assess the properties of a phase or an interface between phases. A system for use in such a method, use of at least one detection molecule for the assessment of a multiphase sample, and a composition for use in the assessment of a multiphase sample are also disclosed.

Abstract: Latently detectable small molecules, or ‘labels’, used for monitoring of treatment substances in fluid conducting and containment systems. A composition comprising the treatment substance and the label, a method of manufacturing the composition, a method and kit for use in monitoring the treatment substances in a fluid conducting and containment system, and a method for treating such a system using the composition are also disclosed.

Abstract: Latently detectable tracers for use in fluid conducting and containment systems wherein the interaction between the tracer and a biomacromolecule produces a detectable signal. More specifically, the latently detectable tracers monitor flow through such systems. Methods for monitoring the flow of fluid using the tracers, and a kit for use in monitoring the flow of fluid in such systems, including the tracers are also disclosed.
