摘要： 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 reacted sample to the illumination detector. A controller is coupled to the illumination source and the illumination detector. The controller is configured to generate an analytic output based on a signal from the illumination detector. A fill conduit is operably interposed between the reaction chamber and the measurement cell. The fill conduit is configured to reduce bubbles.

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.

摘要： A bioreactor sensing system is presented. The bioreactor sensing system comprises a bioreaction vessel. The bioreaction vessel comprises an aperture configured to provide an interface for monitoring contents within the bioreaction vessel. The bioreaction vessel also comprises a port coupled to the bioreaction vessel proximate the aperture. The bioreactor sensing system also comprises a sensing device disposed at least partially within the port such that a sensing element is exposed to the contents. The bioreactor sensing system also comprises an external seal configured to be applied over a portion of the sensing device and a portion of the port.

摘要： A wet chemistry analyzer is provided. The wet chemistry analyzer comprises a reaction chamber configured to receive a reactant solution from a sample inlet and facilitate a process reaction. The wet chemistry analyzer also includes a detection chamber configured to receive a portion of a reaction mixture from the reaction chamber and measure a concentration of a chemical within the reaction mixture. The reaction chamber and the detection chamber are fluidically coupleable such that a portion of the reaction mixture can be directed to flow into the detection chamber to pre-condition a surface inside the detection chamber.
