2.4.4 Internal Peristaltic Pump
The AS-HV rinse station includes a built-in peristaltic pump that provides
a supply of fresh rinse fluid to the reservoir (see
page 7 ). The pump is
controlled through Relay A.
If the rinse station is connected directly to an external rinse source, the
peristaltic pump can be replumbed for use as the sample loading pump in
either the push or pull mode (see
Section 2.3 ). For replumbing
instructions, refer to Section B.3.12 .
To ensure optimal performance when using the internal peristaltic pump
for sample loading, the delivery pressure should be less than 0.03 MPa
(5 psi).
2.4.5 Relay-Controlled Pump
An external relay-controlled pump from a third-party vendor can be used
for sample loading in either the push or pull mode (see
Section 2.3 ). The
pump is controlled through Relay B.
A relay cable connects the pump to the I/O port on the AS-HV side panel
(see Section 2.2 ). Note that the pump is supported by Chromeleon,
although only through relay control.
If you have a question regarding the use of third-party pumps with the
AS-HV, please contact Dionex. In the U.S., call 1-800-346-6390 and
