    • A multi-channel microarray reader has a light source carried by a first supporting stage, a second supporting stage having a plurality of reaction assembly receiving positions, each position to receive a reaction assembly, wherein each reaction assembly includes a reaction chamber and an optical substrate to support a microarray chip, and wherein the reaction chamber and the optical substrate encapsulate a buffer solution. The reader also includes an imaging sensor positioned to detect fluorescence emitted from a single microarray chip and a motion control module to position at least one of the first and second supporting stages to cause a selected microarray chip to receive energy emitted from the light source and to position the imaging sensor to receive fluorescence from that microarray chip.

    • A method and apparatus for determining the concentration of one or more microbes in a sample is provided. This method involves filtering a sample through a filter inside a sample tube to retain the one or more microbes on the filter. The resulting filtrate, which contains or produces adenosine triphosphate, is passed through the sample tube and enters the reporter region. In the reporter region, the adenosine triphosphate in the filtrate comes in contact with a transparent porous matrix, which includes a luciferin-luciferase complex. The adenosine triphosphate interacts with the luciferin-luciferase complex to provide light response, which is measured by a detector. The light response is compared with a calibration curve to determine the total concentration of one or more microbes in a sample.
    • 提供了用于确定样品中一种或多种微生物浓度的方法和装置。 该方法包括通过样品管内的过滤器过滤样品以将一种或多种微生物保留在过滤器上。 将含有或产生三磷酸腺苷的所得滤液通过样品管并进入报道区。 在报道区域中,滤液中的三磷酸腺苷与透明的多孔基质接触,该基质包括荧光素 - 荧光素酶复合物。 三磷酸腺苷与荧光素 - 萤光素酶复合物相互作用以提供光响应,其由检测器测量。 将光响应与校准曲线进行比较,以确定样品中一种或多种微生物的总浓度。
