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 techniques. 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
thoroughly 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 samples, you should increase the
Sample Flush-Out Factor to obtain the desired degree of
flushing to prevent sample carry-over.
Overlapped Injection Mode: provides faster throughput
of samples by allowing the preparation of the next
injection while the current injection is being completed.
The following 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.
