Standard solution with cleaning reagent for wet chemistry analyzer

1. A calibration solution for a wet chemistry analyzer, the calibration solution comprising:

a calibration agent;

a cleaning agent comprising a strong base; and

wherein the cleaning agent is selected such that the wet chemistry analyzer is simultaneously cleaned and calibrated.

2. The solution of claim 1 , wherein the cleaning agent is selected at least in part based on a reagent used in the wet chemistry analyzer.

3. The solution of claim 1 , wherein the cleaning agent comprises sodium hydroxide.

4. The solution of claim 3 , wherein the cleaning agent comprises at least 0.01% by weight sodium hydroxide.

5. A wet chemistry analyzer comprising:

a reaction chamber configured to house a reaction mixture and configured to conduct a reaction with a reagent within the reaction mixture;

a detector configured to detect a process variable indicative of the reaction mixture;

a reagent housing configured to house a calibration fluid; and

wherein the calibration fluid comprises a calibration agent and a cleaning agent, and wherein the calibration fluid is configured to simultaneously clean and calibrate the wet chemistry analyzer during a calibration cycle.

6. The analyzer of claim 5 , wherein the calibration fluid comprises a cleaning agent.

7. The analyzer of claim 6 , wherein the cleaning agent is selected to react with a component of the reaction mixture.

8. The analyzer of claim 6 , wherein the cleaning agent comprises a strong base.

9. The analyzer of claim 6 , wherein the cleaning agent comprises a strong acid.

10. The analyzer of claim 5 , wherein the calibration cycle comprises providing the calibration fluid through the analyzer such that it fluidically contacts a surface configured to receive the reaction mixture.
