Laser-Scatter Measurement Instrument Having Carousel-Based Fluid Sample Arrangement

摘要

An instrument determines a concentration of bacteria in a plurality of fluid samples, and comprises a housing, a rotatable platform, a plurality of fluid containers, a light source, a sensor, and a motor. The rotatable platform is within the housing. The fluid containers are located on the rotatable platform. Each fluid container holds a corresponding one of the plurality of fluid samples, and has an input window and an output window. The light source provides an input beam for transmission into the input windows of the fluid containers and through the corresponding fluid samples. The input beam creates a forward-scatter signal associated with the concentration of bacteria. The motor rotates the rotatable platform so that the input beam sequentially passes through each fluid sample. A sensor within the housing detects the forward-scatter signal exiting from the output window associated with the fluid sample receiving the input beam.

1. An optical measuring instrument for determining a concentration of bacteria in a plurality of fluid samples, comprising:
a housing; a rotatable platform within the housing; a plurality of fluid containers coupled to the rotatable platform, each of the fluid containers holding a corresponding one of the plurality of fluid samples, each of the fluid containers having an input window and an output window; a light source within the housing for providing an input beam for transmission into the input windows of the fluid containers and through the corresponding fluid samples, the input beam creating a forward-scatter signal associated with the concentration of bacteria; a motor for rotating the rotatable platform so that the input beam sequentially passes through each of the plurality of fluid samples; and at least one sensor within the housing for detecting the forward-scatter signal exiting from the output window associated with the fluid sample receiving the input beam.
