ANALYZER OPERATION
Figure 15.
Sample flow during normal operation.
The 9032X Sodium analyzer system is comprised of a stainless steel backplate. The
internal hydraulic components and pipe work are mounted directly onto the metal
backplate. Sample enters through the inlet compression fitting at the bottom of the
case and first passes through the sample flow switch before going to the heat
exchanger. The heat exchanger is used to keep the sample temperature and calibration
solutions temperature at equilibrium during calibration. Drastic and sudden changes in
solution temperature may have a negative effect on electrode performance.
After flowing through the heat exchanger, the sample passes through a constant head
(the constant head unit stabilizes the effect of changes in sample inlet flowrate) and
then through the 3 solenoid valves. After flow passes through the third solenoid valve
(valve furthest to the left) it is then delivered to the entrainment ‘T’ where an alkaline
