Principle of Operation
Typical Spray
A typical spray is illustrated in Figure 11 .
The initial position of the HPLC-Chip tip should be in horizontally centered
between end cap and counter electrode. Vertically, the tip should be at the
same level as the top counter electrode.

If necessary, the tip position can be adjusted via ChemStation (vertical axis)
or manually (horizontal axis). See
Service manual
for details
For tips on spray optimization see Chapter 5 , “The key factors for spray
formation and stability are the liquid flow and capillary voltage setting.,”
starting on page 67.
