To stop a Stat run:
1. Press Stop Run. A prompt appears:
Do you really want to stop the Auto Run?
2. Press Yes to stop the run and return to the Main Menu.
4.8 Sampling Considerations
The sample and chromatography method you use may require changing the configuration
of the autosampler. This section covers:
• Setting the temperature control for the sample compartment
• Making microbore (less than 5 µL) or semiprep (greater than 250 µL) injections
• Injecting viscous samples
• Purging during an auto run
• Using buffered mobile phases
4.8.1 Temperature Control
The heater/cooler module provides sample compartment temperature control from
4to40° C.
Environmental Restrictions
Ambient temperature must be 16 to 27° C at less than 80 percent relative humidity. At
higher ambient temperatures, cooling capacity may be degraded.
Note: Ensure that ventilation space is maintained (see Section 2.1,
Site Requirements).
To control sample compartment temperature:
1. When changing set point from below ambient to above ambient temperature, defrost
the heater/cooler to prevent moisture build up inside the sample compartment (see
Section 5.1,
Defrosting the Heater/Cooler).
