Fitting the ESI probe tip and gasket

Required materials

• Chemical-resistant, powder-free gloves
• 10-mm open-end wrench
• 7-mm open-end wrench
• New metal gasket

To fit the ESI probe tip and gasket:
 Warning: To avoid personal contamination with biologically hazardous materials, wear clean, chemical-resistant, powder-free gloves when performing this procedure.
 Warning: To avoid puncture injuries, handle sample needles, syringes, fused silica lines, and borosilicate tips with extreme care.
Notice: To avoid damage, do not reuse metal gaskets. Always fit a new gasket.

1. Fit the new metal gasket into the probe tip.

2. Fit the probe tip and screw the tip onto the probe assembly.
3. Use the 7-mm wrench in conjunction with the 10-mm wrench to tighten the probe tip.

Important: To avoid gas leakage, fully tighten the probe tip.

4. Fit the ESI probe adapter to the source (see Installing the probe adapter).
5. If required, re-optimize the probe position.
