An analytical instrument measures dissolved carbon in a sample liquid. A syringe pump selectively pumps liquids from valve inlets to a first valve outlet. A sparger receives a sample liquid and a base liquid from the first valve outlet and provides purgeable organic carbon POC gasses. A chemical reactor receives the POC gasses and generates carbon dioxide CO2. A controller coupled to the analytical instrument provides a control actuation sequence to a valve control input and a pump control input. The CO2 couples to an analyzer. The controller generates a first analyzer output that represents a concentration of dissolved POC in the sample liquid.
