3.2 Product overview

The 9525sc degas system removes CO

2

and measures degassed conductivity from the sample

stream. The 9525sc degas system boils the sample and distills the liquid through the crossover

system to remove CO

2

gas from the sample stream. The unit removes CO

2

gas through the steam

vent, and distills the flow through the sample cooler. The unit then measures the conductivity of the

sample.

Use the 9523sc cation conductivity panel to measure specific, cation and degassed conductivity. The

combined system is known as the 9525sc degas cation conductivity (DCCP) system. Refer to

English

Notes:

• The power indicator light will start and stop with the heater.

• For units installed in a small shelter or prefabricated structure, it is recommended that the steam

vent is pointed to the outer side of the structure.

The heater temperature is factory-programmed at 108 °C (226 °F) at the factory and the sample flow

rate must be between 100 and 150 ml/minute (6 and 9 L/hr). Decrease the flow rate if there is no

vapor at the steam vent. Droplets of hot boiling water at the steam vent shows that the distilled water

is too hot. If the distilled water becomes too hot, decrease the set temperature or increase the flow

rate within the specified range.

Refer to Figure 9 on page 16.

1. Set the water flow to the cooler to on.

2. Examine cooler for leaks at the two cooler inlets and the outlet.

3. Examine the outlet tube for correct drainage.

4. Set the sample flow to on.

5. Adjust the sample flow to 100 to 150 ml/minute.

6. Look for leaks and for correct drainage.

7. Set the temperature controller power switch to on. Refer to Figure 8. The power light comes on.

8. Make sure that the display on the controller is on.
