This function can be used with both isothermal and
programmed methods. Post run is a period that begins at the
end of the normal run. The parameters include:
• Time—How long is the post run period?
• Oven Temperature—What is the oven temperature during the
post run period?
• Column n pres—For a column controlled in a pressure mode,
enter the pressure for this column during the post run
period.
• Column n flow—For a column controlled in a flow mode,
enter the flow rate for this column during the post run
period.
• Enable Front inlet temp—For the Multimode inlet, set the post
run inlet temperature. You can also press [On/Yes] and
[Off/No] to turn this parameter on or off.
• Enable Front inlet total flow—For the Multimode inlet, set the
post run inlet total flow rate. You can also press [On/Yes]
and [Off/No] to turn this parameter on or off.
Post run may be used to clean out a column in preparation
for the next run, backflush a column to eliminate
high- boilers, and other functions.
When the Post run Time elapses, the GC returns to the initial
state defined in the current method. If it uses cryogenic
cooling and you do not start another run quickly, you could
waste considerable coolant while waiting for the next run. A
solution is to use a sequence that loads a less wasteful
method.

[Enter]. The post run parameters available for the current
GC configuration appear.
3 Scroll to each desired parameter, type the value for the
post run period, and press [Enter].
Press [Post Run].
