Field Description
injection positions, entering the wrong position will
cause the sample line to be skipped and a “Bad
Injector” message entered into the message log.
To run samples in Duplicate Mode or Dual Mode, you
must select either “1 then 2” or “2 then 1”.
2nd Injection
(Duplicate Mode or Dual
Mode operation only)
Duplicate, Advance, Clean & Dup, or Clean & Adv
Specifies the action that the 8400 will take before
making the second injection during a run.
If you choose “Duplicate” or “Clean & Dup”, the same
sample will be used for both injections. This is called
Duplicate Mode.
If you choose “Advance” or “Clean & Adv”, the 8400
will advance to the next vial location and will sample
the vial, if any, that is there for the second sample
injection. This is called Dual Mode.
Injection Delay
(Duplicate Mode or Dual
Mode operation only)
0.0 and 0.1 through 10.0 minutes
Sets the time delay between the first injection and the
second injection in Duplicate Mode and Dual Mode
operation. When the value is 0.0, the injection time
delay is turned off and not used. For values other
than zero, the 8400 will prepare and load the syringe
for the second injection. When the syringe is loaded,
it will move to the inject position and wait for the
injection delay to time out before injecting.
If the injection delay times out before the sample is
injected, an error message saying that the injection
delay timed out before injection is placed in the
message log.
