3. Check the waste line over the entire flow path:
a) Make sure that no bending, pinching or squeezing of the waste
line is present at any point in the flow path.
b) If you have to cut tubing to length, use a tubing cutter. Make
sure that the cut is at right angle to the length of the line.
When cutting the waste line to length, also make sure that the
cut is not crimped.
The waste line should go straight to the system base and to
waste. Make sure that the line is positioned straight in the
tubing guides.
5.6.5 Connecting the Inlet Capillary to the Nebulizer
Depending on the modules in your Vanquish system, you can connect
the inlet capillary to the nebulizer as follows:
• Directly from the column,
–or–
•
From the flow cell of a first detector, such as the diode array
detector, in the Vanquish system flow path (series flow connection).
In a series liquid flow configuration, one flow path from the pump is
used for both detectors installed in the system.
Parts required
Inlet capillary for connection to the nebulizer (shipped with the
detector)
TIP Keep the capillary connection to the charged aerosol detector as
short as possible to minimize peak dispersion.
Preparations
1. Flush the system modules and capillaries upstream of the detector
to waste thoroughly before you connect the detector to the system
flow path. Refer to the
Vanquish System Operating Manual
.
2. On the nebulizer, remove the plug from the nebulizer flow inlet.
