    Abstract: A colorimetric wet chemistry analyzer for determining a concentration of an analyte of interest in a sample is provided. The analyzer comprising includes a reaction chamber configured to receive the sample and facilitate a reaction that changes a color of the sample based on the concentration of the analyte of interest. A photometric cell is operably coupled to the reaction chamber to receive the sample and direct illumination therethrough. The photometric cell has a first illumination source configured to provide illumination at a first wavelength through the photometric cell and a second illumination source configured to provide illumination at a second wavelength through the photometric cell. The second wavelength is different than the first wavelength. A photo detector is configured to detect illumination passing through the photometric cell. A controller is coupled to the first illumination source, the second illumination source and the photo detector and is configured to provide an indication of concentration relative to the analyte of interest based on a signal from the photo detector.

    Abstract: 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.

    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.

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.
