Abstract: The invention relates to a sample device that allows for simultaneous analysis of multiple liquid samples (e.g., drinking water samples). More specifically, the sample device is adapted for use with a mobile water analyzer, the sample device including an upwardly open receptacle divided into a plurality of separate upwardly open compartments separated by dividing walls. Each of the compartments is configured to contain a separate water sample, and the sample device is adapted to receive the inlet opening of a removable test element of a mobile water analyzer.

Abstract: A monochloramine microsensor includes an elongated housing defining a central axis and an open interior and having a capillary opening at one end. A semi-permeable membrane covers the capillary opening, the semi-permeable membrane allowing diffusion of chloramines there-through while preventing water from entering into the interior of the housing. A chloramine sensitive element in the form of a wire, fiber or nanotube is mounted within the housing, the chloramine sensitive element, when used in conjunction with an anode, outputs current in an amount proportional to the concentration of chloramine present in a liquid sample in which the chloramine sensitive element is immersed. The chloramine sensitive element extends along a length of the central axis to a first end adjacent to and spaced from the semi-permeable membrane. The chloramine sensitive element is a gold wire, a platinum wire, a carbon fiber or a carbon nanotube.
