    Abstract: A colorimetric analyzer includes a reaction chamber configured to receive a sample and at least one reagent. A measurement cell is operably coupled to the reaction chamber. The measurement cell has an illumination source and an illumination detector spaced from the illumination source such that illumination from the illumination source passes through the measurement cell to the illumination detector. A controller is coupled to the illumination source and the illumination detector. The controller is configured to determine an absorbance of a reducing reagent and store the determined reagent absorbance in the analyzer. The controller is configured to use the determined reagent absorbance to compensate at least one subsequent colorimetric sample measurement.

  • Patent number: 9891162
    Abstract: An online colorimetric analyzer that generates an indication of a material in a sample is provided. The analyzer includes a peristaltic pump configured to convey. A photometric cell is operably coupled to the peristaltic pump to receive the sample. An illumination source is disposed to direct illumination through the sample in the photometric cell along an angle of incidence. A photodetector disposed to receive illumination passing through the photometric cell along the angle of incidence and provide a signal indicative of a color of the sample. A controller is coupled to the illumination source, the photodetector and the peristaltic pump. The photometric cell is tilted relative to vertical such that a surface of liquid present when the photometric cell is partially filled substantially reflects the illumination away from the angle of incidence.

  • Patent number: 9868930
    Abstract: A single use pH sensor housing for a single use container is provided. The single use pH sensor housing includes a compartment configured to house a single use pH sensor. In one embodiment, the single use pH sensor housing comprises an actuator configured, when actuated, to transition the single use pH sensor from a storage position to a deployed position. In the storage position, the pH sensor is in fluidic contact with a buffer solution. In the deployed position, the single use pH sensor is in fluidic contact with an interior of the single use container. During the transition from the storage position to the deployed position, the buffer solution moves from a sensor portion of the compartment to a storage portion of the compartment such that the buffer solution is isolated from contact with the interior of the single use container.
