Connecting the Pump to the Autosampler
The Accela System Kit contains 1/16 in. OD
×
0.005 in. ID stainless steel tubing precut to
20 cm and high-pressure fittings. These items are used to connect the outlet of the Accela
Pump to the heat exchanger of the Accela Autosampler.
If you have an older version of the Accela Pump that does not have an integrated mixer, you
can order the Accela Pump Dynamic Mixer Upgrade Kit to upgrade the pump, or you can use
the precut, 20 cm length of high-pressure tubing to connect the outlet port of the inline filter
holder directly to the heat exchanger of the Accela Autosampler.
Figure 17
shows the high-pressure fitting supplied in the system kit. This fitting consists of a
nut, a back ferrule, and a front ferrule.

To connect the Accela Pump to the Accela Autosampler
1. Place the Accela Autosampler on top of the Accela Pump.
The Accela Pump is shipped with the LDA outlet connected to the inline filter holder
inlet and the inline filter holder outlet connected to the mixer inlet. You might need to
reconnect the inline filter holder after performing maintenance on the liquid
displacement assembly (LDA).
2. Connect the pump to the autosampler as follows:
a. (Factory installed) Using a precut, 10 cm length of high-pressure tubing and a
high-pressure fitting, connect the LDA to the inlet of the inline filter holder (see
Figure 18
).
b. (Factory installed) Using a precut, 5 cm length of high-pressure tubing and a
high-pressure fitting, connect the outlet end of the filter holder to the mixer inlet (see
Figure 18
).
c.
Using a precut, 20 cm length of high-pressure tubing and a high-pressure fitting,
connect the mixer outlet to the inlet of the autosampler heat exchanger. If the pump
does not have a mixer, connect the outlet end of the filter holder to the inlet of the
autosampler heat exchanger.
