5. Remove the O-rings from the capillary inlet cone.
1. Remove the O-ring under the capillary base, then sonicate
the capillary in a methonal:water (50:50) mixture for
30 minutes (Figure 5-14).
2. If heavily contaminated, sonicate in methanol:water + 1%
formic acid (50:50) mixture for an hour.
3. Rinse the capillary thoroughly with acetone, isopropanol,
and methanol, then dry the capillary using nitrogen air.
1. Ensure that the O-ring seals are in position.
2. Place the capillary inlet cone into the opening and press
down until the threads are able to engage. There may be
slight restriction in a downward motion as the part is
almost completely inserted. This restriction is caused by
the capillary opening the valve to the vacuum region.
3. Screw the capillary inlet cone into the inlet. Finger tight is
sufficient as long as the part is fully seated.
4. Replace the ion source.
5. Place the PurIon in the operate mode.
If your instrument stops working and the touch panel display is
off, check the line cord connection.
If the line cord is connected properly, check circuit breaker on the
system's rear panel to ensure it is switched to the O
EAR99 Technology Technology Subject to Restrictions Contained on the Cover Page
position.
