SENSING ASSEMBLY

The present disclosure provides a sensing assembly for sensing a property of a fluid sample comprising at least one working electrode provided in the primary fluid channel configured to sense a property of a fluid sample in the primary fluid channel; a secondary fluid channel adjacent to and fluidly connected to the primary fluid channel along the primary flow path; and a reference electrode element provided in the secondary fluid channel. The secondary fluid channel is arranged as a branch from the primary flow channel so as to limit the flow of fluid sample from the primary flow channel to the reference electrode element. Alternatively or additionally, a method comprises determining a property of a sample comprising providing such a sensing assembly.
