To adjust the emitter tip position
The position of the column holder is now calibrated for use with any EASY-Spray column.
You must repeat this procedure if you later change the
x

y
-, or
z
-axis position.
Tip
To enhance your view of the emitter positioning tool’s tip, install the camera and
LCD monitor (if applicable) before you begin this procedure. For instructions, see
Chapter 3, “Installing the Camera and LCD Monitor.”
IMPORTANT
The fused-silica emitter is fragile. Make sure that the emitter
positioning tool gently touches the ion transfer tube when you adjust its position or
you will damage the actual emitter when fully inserted, requiring you to replace the
EASY-Spray column.
CAUTION High voltage.
To prevent electric shock, never insert a foreign object,
especially a conductive part, into the ion source opening. The opening is intended
only for the emitter positioning tool and the EASY-Spray column.
