Assembling The Source Ion Block Assembly - Waters Xevo TQ-S Operator's, Overview And Maintenance Manual

3. If you used formic acid in the cleaning solution, do as follows:
a. Rinse the components by immersing them separately in glass
vessels containing water and then placing the vessels in the
ultrasonic bath for 20 minutes.
b. Dry the components by immersing them in separate glass vessels
containing methanol and then placing the vessels in the ultrasonic
bath for 10 minutes.
Caution:
chemical-resistant, powder-free gloves for the rest of this
procedure.
4. Carefully remove the components from the vessels, and blow-dry them
using inert, oil-free gas.
5. Inspect each component for persisting contamination. If contamination
is present, do as follows:
a. Use the wash bottle containing 1:1 methanol/water to rinse the
component over the large beaker.
b. Blow-dry the component using inert, oil-free gas.
6. Inspect each component for persisting contamination. If contamination
is present, dispose of the component, and obtain a new one before
reassembly.
