Drop the flow rate to 1 ml/min and close the prime-purge valve to flush the lines to the injector.
If this is an amino acid system, it is highly recommended that you dead-head the pulse dampener of the pump.
This will provide reliable gradient formation, and will prevent corrosion of the low-grade steel used in most
pulse dampeners.
Use one of the two methods below for making the connections. Amino Acid systems must be connected
according to method 2.
1.Connect the outlet of the injector to the inlet of the pre-column check valve assembly.
OR
2.Connect a tee to the inlet of the pulse dampener. Connect a line from the outlet of the pulse dampener to a tee
and place a high-pressure plug in the outlet. Connect the inlet and outlet of the pump through the tee (figure
3-1).
Connect the outlet of the injector to the Check Valve assembly. Use 0.011" ID tubing and a PEEK nut and ferrule.
(PNs 1452-0118, 1452-0117, 2104-0210, 1452-0226)
Place the open end of the check valve tubing into a beaker.
Flush line from injector for 5 minutes at 1 ml/min with 80/20 Water/Methanol.
