<p>A sensor for quantifying the flow rate or viscosity of a fluid sample, or the concentration of an analyte within that fluid sample. The sensor comprises a chamber for holding a fluid sample and guiding it through a channel containing a detection means. The chamber has at least one and preferably two changes in a diameter and the flow of the sample from the chamber thereby causes detectable changes in the readings of the detection means. Given the known chamber dimensions, this enables flow rate and viscosity of a fluid sample to be calculated. This can then be used to calculate the concentration of an analyte, directly or indirectly, despite any flow rate dependency of the detection means.</p> |
