An sensor for determining the concentration of a ketone body in a sample, the sensor comprising a sample chamber having an inlet with a width and a projection extending from an edge of the sensor proximate the inlet, the projection having a width that is less than the inlet width.
A sensor for determining the concentration of a ketone body in a sample, the sensor comprising:
- a first substrate, a second substrate, and a spacer layer therebetween;
- a sample chamber defined between the first substrate and the second substrate bounded by the spacer layer, the sample chamber having at least one inlet;
- a protrusion extending from the first substrate at the inlet.
A sensor for determining the concentration of a ketone body in a sample, the sensor comprising:
- a first substrate and a second substrate;
- a first side edge, a second side edge and an end edge;
- a sample chamber defined between the first substrate and the second substrate, the sample chamber extending from the first side edge to the second side edge;
- a first aperture and a second aperture between the first substrate and the second substrate at the first side edge and the second side edge, respectively;
- and
- at least one protrusion extending from either the first side edge or the second side edge, proximate the apertures.
A method of analyzing a ketone body concentration in a sample comprising:
- contacting a sample with a sensor;
- transferring the sample into a sample chamber through an inlet bounded by at least one protrusion that has a width less than a width of the inlet;
- and
- determining the concentration of the ketone body in the sample.
A method of analyzing a ketone body concentration in a sample comprising:
- contacting a sample with a sensor having a first substrate, a second substrate and a spacer layer therebetween and at least one protrusion extending from one of the substrates;
- transferring the sample into a sample chamber through an inlet bounded by the substrates and the at least one protrusion;
- and
- determining the concentration of the ketone body in the sample.
