Exhaust System
An exhaust system is needed for the iCAP Q MS to remove gases that
may contain ozone and other noxious substances. Two exhaust ports are
situated at the top of the instrument, see
.
The exhaust ports have an outer diameter of 60.3 mm. A flexible duct
with 63 mm inner diameter is recommended for the connection to the
exhaust port. Thermo Fisher Scientific delivers such an exhaust duct
with a length of 6 m. The plasma exhaust duct should be equipped with
a throttle valve.
Other peripheral devices might need additional exhaust connections.
Refer to the manual of these peripheral devices.
NOTICE
Do not switch off the exhaust system when plasma is running.
Plasma will be shut off automatically when the air removal capacity
drops below 36 m³/h.
