Flow path during calibration mode and normal operating conditions
Quantichem® 9031 Sensor Unit
During calibration the 3-way valve is activated, a standard of known sodium concentration passes through a heat exchanger to equilibrate the solution’s temperature to that of the sample. The standard then enters the constant head unit where flow is stabilized. Alkaline buffer vapor is added via a vapor entrainment mechanism before the standard enters the sodium measuring flow cell and flows to drain. During normal operating conditions the standard solution is replaced by the sample.
