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.

Abstract: A milking system includes a milking device with a milking control, a milk line, and a sampling/analysis device. The milking control controls the milking based on said analysis. The sampling/analysis device includes a reagent carrier, including a tape with a first side with a reagent pad that detects the presence of a substance in the milk sample and a second side, a dosing device to provide a droplet of said sample onto the reagent pad, a source for emitting source radiation onto the reagent pad, and a sensor to detect response radiation emitted by the reagent pad, and to analyse the detected response radiation to indicate the presence or concentration of said substance. The first side faces away from the sensor during analysing by the sensor. By viewing “from below”, the observed reaction in the reagent is cleaner, and suffers less from artefacts, and the camera will stay cleaner.

Abstract: A method of producing a reagent tape, that includes a base tape layer and a series of consecutive and separate reagent pads of a reagent, is provided for use in a milk sampling device. The milk sampling device is arranged to supply a droplet of a milk sample onto one of the reagent pads on the tape in order to produce a response in the reagent to detect a presence or concentration of a substance in the milk sample. The method includes providing the base tape layer of the reagent tape, applying onto the base tape layer a continuous layer of the reagent, dividing the supplied continuous reagent layer into separate reagent pads by providing a hydrophobic barrier line between said pads. This may be done by laser ablating thin lines of reagent material, or by providing additional hydrophobic material into the layer. Thus, a simple and fast way of providing a tape with pads is obtained, in which a narrow spacing between pads is possible. A tape made by the method, and a milking device with a sampling device with such a tape are disclosed.
