High Throughput
Injection Valve to Bypass for Delay Volume Reduction: Mark
this check box to switch the flow from the injector from
mainpass (main path) to bypass after injection has taken
place. This reduces the delay volume for low volume tech
-
niques. You can specify the point during the analyses when
the valve switches to bypass by setting the Sample
Flush-out Factor.
Sample Flush-Out Factor: ensures that the sample is thor-
oughly flushed out of the syringe and past the capillary seat
and valve. The Sample Flush-Out Factor is preset to 5.0 at
the factory. The preset Sample Flush-Out Factor is correct
for most methods. However, for unusually viscous sam
-
ples, you should increase the Sample Flush-Out Factor to
obtain the desired degree of flushing to prevent sample car
-
ryover.
Overlapped Injection Mode: provides faster throughput of
samples by allowing the preparation of the next injection
while the current injection is being completed. The follow
-
ing options can be selected from the drop-down list:
•Off: to switch off overlapped injection. Select When
sample is Flushed Out to specify that the sample can
be prepared directly after the current sample has been
flushed out.
•Prefetch Vial: to specify that the next sample is fetched
by the gripper while the current sample is running.
•Overlap Injection Cycle: to specify that the next sample
is fetched and loaded into the sample loop while the
current sample is running. Specify a time (in minutes)
after injection when this process should be started.
