Cleaning the sample cone and gas cone 5-25
5. Carefully remove the components from the vessels, and blow-dry them
with inert, oil-free gas.
6. 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 with inert, oil-free gas.
7. Inspect each component for persisting contamination. If contamination
is present, dispose of the component, and obtain a new one before
reassembling the cone gas assembly.
Caution: To avoid recontaminating the components, wear clean,
chemical-resistant, powder-free gloves for the rest of this
procedure.
