5. Monitor the baseline conductivity. In general, it should be <30
μ
S for a system
set up for anion analyses, and <2
μ
S for a system set up for cation analyses.
2.15 Verifying Operational Status
After the system has equilibrated, verify the actual pump pressure and stability by
monitoring the pump pressure. Record the short-term pressure fluctuations; they
should be less than 0.13 MPa (20 psi).
2.16 Connecting the AS40 Automated Sampler (Optional)
1. Open the front door of the ICS-90 and thread the outlet line from the AS40
through the side slot near the lower ICS-90 door hinge (see Figure 2-17 ).
2. Connect the outlet line from the AS40 to port S (5) of the injection valve (see
Figure 2-21 ).

3. Follow the steps below to connect the TTL Output connector on the ICS-90
rear panel to the
RELAY CONTROL
connector on the AS40 rear panel.
a. Locate the Relay Control cable (P/N 047946) supplied with the AS40.
b. Connect the Relay Control cable's 10-pin connector to the
RELAY
CONTROL
connector on the AS40 rear panel (see Figure 2-22 ).
