5. Feed the blunt end of the emitter tip through the PEEK hex nut and then use the fused silica cutter to trim 1
cm from the blunt end of the emitter tip.
Note:
Score the emitter tip and then pull the waste part laterally, along the axis of the tubing. When using
uncut emitter tips, cut them to approximately 7 cm.
6. Insert the blunt end of the emitter tip into the union.
7. Tighten the PEEK hex nut in the union until it is finger-tight.
Tip!
To eliminate any dead volume inside the union, make sure that the emitter tip is pushed all the way
into the union before tightening the nut.
8. Adjust the position of the union until the emitter tip protrudes 0.5 mm to 1 mm from the sprayer head.
9. Tighten the sprayer fitting.
10. Tighten the union thumbscrew.

ion source
without the illuminator, camera, stop, and covers properly installed. Never
touch the curtain plate or allow the emitter tip to contact the curtain plate.
If the mass spectrometer is operational and the ion source is installed, then
high voltage is present on the curtain plate, even if the X-Y-Z positioning
unit is moved away from the interface.
WARNING! Electrical Shock Hazard. Move the X-Y-Z positioning unit away
from the ion source interface to disconnect the supply of high-voltage power
from the sprayer head and high-voltage rail.
1. Make sure that the X-Y-Z positioning unit is as far from the ion source interface as possible, until it is stopped
by the sleeve, to disable the supply of high-voltage power to the ion source head.
2. Make sure that the illuminator is off. The switch should be in the position furthest from the LED.
3. Turn the Z-axis adjustment knob counter-clockwise as far as it will go. The Z axis should be in the 0 position.
