Abstract: A testing apparatus for performing an assay, the testing apparatus comprising: a receptacle (2) containing a reagent, the reagent being reactive to an applied test sample by developing a colour or pattern variation; a portable device (1), e.g. a mobile phone or a laptop, comprising a processor and an image capture device (3), wherein the processor is configured to process data captured by the image capture device and output a test result for the applied test sample.

Abstract: An acquired image is analysed to determine a test outcome value. A shape template for a test structure is provided to identify a position of a target measurement region on the test structure. A mapping defining a transformation of the shape template onto the image frame is determined. A mapping is determined and it is determined if a first matching condition based on first displacements of one or more edges identified in the image frame relative to the shape template is satisfied for the mapping. When the mapping satisfies the first matching condition and a second different matching condition based on second displacements of one or more edges identified in the image frame relative to the shape template, a verified image of a test structure is established. In the verified image of the test structure a target measurement region is identified. A test outcome value is determined by analysing the target measurement region.

Abstract: A fluid treatment apparatus comprising: a reactor vessel defining a chamber and having an inlet and an outlet to allow fluid to flow through the chamber; a UV light source adapted to transmit light within the chamber; and a plurality of catalyst members comprising a catalytic outer surface, the catalyst members being freely contained within the chamber, wherein the apparatus is adapted to cause the catalyst members to move around within the chamber as fluid flows through the chamber.

Abstract: An improved Surface Plasmon Resonance Sensor (8) is described that is compact, simple to align and cost effective to produce, thus making the device highly mobile and so idea for field applications. These characteristics are achieved through the employment of a pre-formed cartridge (10) that provides for the required manipulation of a beam of light (2) used within the surface plasmon resonance process. The cartridge (10) is easily interchangeable and so provides a high degree of flexibility to the sensor (8). The device therefore provides a fast and simple means for the on site testing of fluids for the presence of harmful fluid borne bacterium. Particular application of the device is the testing of water samples obtained from industrial or recreational sources for the presence of the Legionella bacteria.
