Abstract: A fully functional analyzing unit is included within the fluid-tight housing of a dialyzer which may be immersed in the medium to be analyzed. An opening in the housing is closed by a dialysis membrane. A channel defining body cooperates with the membrane to define a flow channel. The unit includes a carrier fluid reservoir and a carrier pump for generating a flow of carrier fluid through the flow channel. By dialysis via the membrane, the flow of carrier fluid is transformed into a flow of sample fluid which is received in a reaction channel. Reagent fluid from at least one reagent reservoir is delivered to the reaction channel by at least one reagent pump, and a detecting device is coupled to the reaction channel for detecting a reaction product originating from a reaction between the reagent fluid and the sample fluid and for generating a corresponding detection signal. Effluent from the reaction channel is received in a waste reservoir.

A detecting device is coupled to detect an analyte in the sample fluid and for generating a corresponding detection signal. Effluent sample fluid is received in a waste reservoir. The device is suitable for in situ real-time measurement of plant nutrient salts in process waters of waste water treatment plants.

Abstract: The present invention relates to a method of determining physical and/or chemical properties in water samples containing suspended substances and/or particles, the physical and/or chemical properties being singly or jointly determined as amount of nitrate, iron, ammonium, phosphate, total nitrogen or total phosphorous; turbidity, chemical oxygen demand (COD) and/or biological oxygen demand (BOD).

Abstract: A method of reducing the susceptibility to interference of the measured value from a measuring instrument. The measuring instrument is of such a type where a test object is subjected to measurements with respect to a plurality of primary test object properties. Before the actual measurement, the effect has been mapped, by a calibration procedure, which these properties have on the measured value regarding a secondary property of the test object.

Abstract: An instrument adapted to make assessments in sensory evaluation comprises two wafers which are separated by spacers and are provided on their opposing faces with conductive patterns. Upon use, the instrument is connected to a computer which activates one conductor at a time on one side of the instrument and senses if one or more of the conductors on the other side of the instrument are activated, i.e. if a person is exerting a pressure, for example by a finger, at some point or other on the instrument. The special design of the conductive patterns makes it possible to convert the analog position of the pressure into a digital signal which is fed directly into the computer.

Abstract: For determining both water-insoluble and water-soluble plant fibre components in plant fibre material, more particularly dietary fibre components in dietary plant material, a sample which has been solubilized and degraded with regard to other plant components is passed through a glass filter (2) capable of retaining the water-insoluble fibre components of the sample and then through an ultrafilter (1) capable of retaining the water soluble fibre components and the sample.
