Temperature Control
The following temperature control zones are possible with the DC, depending on
the options installed:
•
In the single-zone (shared) configuration, the upper and lower compartments
are in the same temperature zone. The temperature can be set to between
15 and 40 °C. Air flow passages between the compartments allow the
temperature to stabilize equally in both compartments.
•
In the dual-zone configuration, the lower compartment is isolated from the
upper compartment in a separate temperature zone. There is no common air
flow between the upper and lower compartments. The temperature of the
lower compartment can be set to between 10 and 70 °C. The temperature of
the upper compartment can be set to between 15 and 40 °C.
•
When a CD is installed, the heated conductivity cell can be set to 5
°
C
above
the upper compartment temperature
,
up to 60 °C.
•
If an RCH-1 Reaction Coil Heater is installed in the AM, the temperature of
the RCH-1 heater can be set to 5
°
C above the upper compartment
temperature, up to 80 °C.
The temperatures achieved for a particular zone can vary from the control range,
depending on the ambient temperature (see the table below).
For example, if the ambient air temperature in your lab is 30 °C and you set the
upper compartment temperature to 15 °C, the actual temperature achieved in the
upper compartment will be about 20 °C.
