The invention relates to a method suitable for detecting, capturing and/or selectively releasing chemical elements selected from poor metals, alkalines, alkaline earths, actinides and rare earths. Said method involves a molecular assembly formed by at least one amine, and at least one aldehyde and/or an imine and/or CO.sub.2, or an adduct formed by the contact between an amine and CO.sub.2, and at least one of said chemical elements. The invention also relates to a kit for implementing said method for detection, capture and/or release.

Methods, apparatuses, and kits for detection of substances in water by forming a complex with an indicator reagent and filtering the complex on a filter or membrane are described. The concentrated indicator on the filter, membrane or other capture device provides a colorimetric readout that can determine the amount of substance present in a water sample. A computer-implemented method for determining the concentration of substances in water based on color data from the colorimetric readout is also described.

The present invention relates to determining phase information of a fluid sample. At least one image of the fluid sample including the phase information of the fluid sample is provided. Additionally, a data driven model which comprises at least one output channel for the phase information is provided. The at least one output channel includes at least one output channel for classifying a boundary between two phases of the fluid sample, such that the phase information includes information about a property of the boundary between the two phases, such as a height, a volume, a type, or a strength of the boundary. The phase information of the fluid sample is derived based on the data driven model and the at least one image of the fluid sample including the phase information of the fluid sample.
