Setting Up a Sequential Mode Injection
The AS must be equipped with the sequential injection option
(P/N 063294) in order to perform sequential injections. The following
setup steps are required:
1. Follow the instructions in Section B.3.6 to install the sequential
injection diverter valve, connect the AS inject port tubing to the
diverter valve, and connect the diverter valve to the injection valves
on two systems.
2. Calibrate the inject port volume of each system. This is the volume
from the inject port through the diverter valve to the injection valve
(see
Section 5.9 ).
3. On the
SYSTEM PARAMETERS
screen, select
SEQUENTIAL
in the
SAMPLE MODE
field (see Figure 3-27 ).
4. On the
PLUMBING CONFIGURATION
screen, enter the sample loop size
installed on each valve (see Figure 3-28 ).
