 To clean the spray cone and O-ring
IMPORTANT Always use LC/MS-grade methanol and LC/MS-grade water (see
Table 7 on page 55).
1. Soak Kimwipe tissues or chamois-tipped swabs in a 50:50 solution of methanol/water,
and then clean the exterior surface of the spray cone.
2. Remove and inspect the O-ring that is in the spray cone under the entrance end of the ion
transfer tube (Figure 62
