A wet chemistry analyzer (100) is provided. The wet chemistry analyzer (100) comprises a reaction chamber (102) configured to receive a reactant solution from a sample inlet (112) and facilitate a process reaction. The wet chemistry analyzer (100) also includes a detection chamber (118) configured to receive a portion of a reaction mixture from the reaction chamber (102) and measure a concentration of a chemical within the reaction mixture. The reaction chamber (102) and the detection chamber (118) are fluidically coupleable such that a portion of the reaction mixture can be directed to flow into the detection chamber (118) to precondition a surface inside the detection chamber (118).
