Valve Types
The possible valve types are:
Sampling A two-position (load and inject) valve. In load
position, an external sample stream flows through an attached
(gas sampling) or internal (liquid sampling) loop and out to
waste. In inject position, the filled sampling loop is inserted into
the carrier gas stream. When the valve switches from Load to
Inject, it starts a run if one is not already in progress. See the
example on page 115.
Not installed Self-explanatory.
