Follow these steps
1. On the Evaporation Temperature screen, set the evaporation
temperature. To optimize the evaporation temperature for your
application, observe the guidelines in
section 6.7.4, page 142 .
2. To deliver pump flow to the charged aerosol detector, follow these
steps:
a) Make sure that the pump flow rate limit is set to the maximum
flow rate specified for the charged aerosol detector.
b) Turn on the pump flow to the detector. Have the pump deliver
flow to the detector.
Observe the Mobile Phase Guidelines for the Detector in
section 6.5.1, page 123 .
The following table provides an overview of typical flow rates for
certain column internal diameters:
Column Inner Diameter Typical Flow Rate
4.6 mm 1.0 mL/min
3.0 mm 0.5 mL/min
2.0 mm 0.2 mL/min
1.0 mm 0.05 mL/min
3. Allow the detector to equilibrate until you observe a steady
baseline.
♦
Monitor the background signal of the detector. It will increase
initially and should then start to fall. Over a short period of time,
the signal should fall to a low level and then stabilize.
♦
The detector is ready for data acquisition when the baseline is
stable. The time required to obtain a stable baseline depends on
the application.
4. Perform an autozero of the detector baseline. In the
Run Mode
Menu of the display, press the Autozero soft key.
The detector is now ready for sample analysis.
