On-line wet chemistry analyzer
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.
1. A wet chemistry analyzer comprising:
a reaction chamber configured to receive a reactant solution from a sample inlet and facilitate a process reaction;
a detection chamber, fluidically connected, through a first three-way valve to the reaction chamber, wherein the detection chamber is configured to receives a portion of a reaction mixture from the reaction chamber while the process reaction is ongoing and before the process reaction is completed; and
wherein the reaction chamber and the detection chamber are fluidically connected, through the first three-way valve, wherein the portion of the partially reacted reaction mixture is provided to the detection chamber and is configured to pre-condition a surface inside the detection chamber while the process reaction is occurring in parallel and proceeds to completion.
2. The analyzer of claim 1 , and further comprising:
a gas inlet fluidically connected to the reaction chamber, through a second three-way valve, wherein a gas flows into the reaction chamber from the gas inlet.
3. The analyzer of claim 2 , wherein the gas flows into the reaction chamber at a position that it facilitates mixing within the reaction chamber.
4. The analyzer of claim 2 , wherein the gas flows through the reaction chamber and the detection chamber and facilitates a partial removal of the portion of the reaction mixture from the detection chamber, through a third three-way valve, after the detection chamber surface is pre-conditioned.
5. The analyzer of claim 1 , wherein the first three-way valve is alternatively causes a coupling between the detection chamber and either a liquid holding portion of the reaction chamber or a gas holding portion of the reaction chamber.
6. The analyzer of claim 1 , wherein the detection chamber is also fluidically connected to a waste stream, through a third three-way valve that facilitates removal of the portion of the reaction mixture from the detection chamber prior to a second portion of the reaction mixture entering the detection chamber.
7. The analyzer of claim 1 , wherein the reaction chamber is coupled to the detection chamber, and wherein the portion of the reaction mixture enters the detection chamber without significant disturbance to the ongoing process reaction.
