Feed the sample capillary through the probe, ensuring that a 0.4mm graphitised
vespel ferrule (GVF/004) is fitted.
Using a ceramic capillary cutter, cut the capillary at the nebuliser so that
between 0.5 and 1.0mm of capillary is protruding from the nebuliser.
It is important to cut the capillary square. This should be examined using a
suitable magnifying glass.
Undo the adapter nut from the probe and withdraw the capillary from the probe.
Remove 20mm of polyamide coating from the end of the capillary using a flame
and clean with a tissue saturated with methanol.
Carefully re-feed the sample capillary through the probe ensuring that the
graphitised vespel ferrule is still fitted.
Using a Rheodyne spanner, gently tighten the adapter nut to the probe.
Replace the probe end cover and retaining screws.
Using a 1.5mm Allen key, tighten the grub screw in the probe end cover to
clamp the filter.
Replace the heater and probe tip assembly.
