Theory of operation

The analyzer uses a pressurized reagent system and solenoid valves to supply sample, reagents
and calibration solutions to the sample cell. At the start of each measurement cycle, sample flows
into the sample cell. When the sample cell is full, reagents flow into the sample cell. A stirrer mixes
the reagents with the sample. The stirrer stops to let the mixture become stable and to let air bubbles
dissipate. The analyzer measures the color of the sample. When the measurement is complete, new
sample flushes the sample cell, and the measurement cycle starts again.
