Fitting the ESI probe tip and gasket
Required materials
• Chemical-resistant, powder-free gloves
• 7-mm wrench
• New metal gasket
To fit the ESI probe tip and gasket
:
1. Fit the new metal gasket into the probe tip.
2. Fit the probe tip (a new one if you disposed of the old) over the capillary,
and screw the tip onto the probe assembly.
3. Use the 7-mm wrench to tighten the probe tip.
4. Use the nebulizer adjuster knob to adjust the capillary so that it
protrudes by approximately 0.5 mm from the end of the probe.
5. Fit the ESI probe onto the source (see page 58 ).
Warning:
To avoid personal contamination with biohazards or
toxic materials, and to avoid spreading contamination to
uncontaminated surfaces, wear clean, chemical-resistant,
powder-free gloves when working with the probe and source
components.
Warning:
To avoid puncture wounds, handle the probe with care;
the ESI probe tip is sharp.
Notice:
To avoid gas leakage, fully tighten the probe tip.
