Controls and connections on the top of the instrument
Probe cooling water connections and gas flow valves
Probe cooling water connections
The cooling water connections (one inlet and one outlet) provide cooling water
for the solids sample introduction probe.
See the figure “Front view of the instrument” on page 1-6 and “Making the
probe cooling water connections” on page 6-5.
Gas flow valves
Use the CI gas flow valve to control the flow of CI gas to the source. Two
concentric knobs provide coarse and fine control of the gas.
Use the FFR1 gas flow valve to control the flow of collision gas to the first
field-free region.
See the figure “Front view of the instrument” on page 1-6.
