Method and apparatus for sensing ion concentrations in a fluid sample

摘要

A method for conducting a measurement on a sample using a disposable apparatus (2) is disclosed. The method comprises removing a cover layer (40) from a partly permeable layer (30) comprising one or more holes providing fluidic access to at least one channel (12). The channel (12) is filled with a background solution and is otherwise sealed. The method further comprises providing a sample onto a surface of the partly permeable layer (30), allowing components of the sample to pass through the partly permeable layer (30) into the at least one channel (12), and determining at least one property of the components of the sample.
