High Throughput
Injection Valve to Bypass for Delay Volume Reduction:
Mark this check box to switch the flow from the injector
from mainpass 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.
