Abstract
A milking system including a milking means, a milk line, and a sampling and analysis device, that includes an analysis tape, with a carrier layer and a reagent tape layer with a reagent that provides a detectable response in the presence of a substance in the sample, a dosing device, an optical radiation source, and an optical sensor device to detect optical response radiation emitted by the reagent tape layer and to analyse the detected optical response radiation to provide an indication of a presence or concentration of the substance in the droplet. The reagent tape layer includes, or is, a material with an asymmetrical porosity, having the largest pore size at a first side where the sample is provided, and the smallest pore size at the opposite side.
Claims7
A milking system, comprising:
- a milking means comprising a milking control device, and arranged for milking milk from a dairy animal;
- a milk line in fluid connection with the milking control device;
- and
- a sampling and analysis device arranged to take a sample of the milk from the milk line and to analyse the sample,
- wherein the sampling and analysis device comprises
- an analysis tape, comprising a carrier layer with a first side and an opposite second side, wherein on the first side there is provided at least one reagent tape layer comprising a reagent that is arranged to provide a detectable response in the presence of at least one substance in the sample;
- a dosing device arranged to provide a droplet of said milk from said sample onto the reagent tape layer;
- an optical radiation source for emitting optical source radiation onto the analysis tape;
- and
- an optical sensor device arranged to detect optical response radiation emitted by the reagent tape layer along an optical path to the optical sensor and in response to said emitted source radiation received by said reagent tape layer, to analyse a detected optical response radiation to provide an indication of a presence or a concentration of said at least one substance in said droplet,
- wherein the carrier layer is transmissive to the optical radiation,
- wherein the first side faces away from the optical path to the optical sensor device during analysing by the optical sensor device, and
- wherein the reagent tape layer comprises, or is, a material with an asymmetrical porosity, having a largest pore size at the first side, and a smallest pore size at the second side.
