2.6.4 Connection injection valve → suppressor
The precolumn and the separating column are fitted between injection
valve and suppressor in the operational system (see Figure 3). How-
ever, since the system should first be rinsed without columns (so as not
to damage them), the columns may be fitted only later (see Section
2.15). A PEEK coupling 54 is fitted as a temporary replacement.
Proceed as follows:
1 Fit the PEEK coupling 54
Connect the column connection capillary 33 to the "suppressor
inlet capillary for eluent ("Eluent")" 37 via the PEEK coupling 54
(see Section 2.3.2).
Temporary connection schematic (c.f. Figure 3):
2.6.5 Connection suppressor → detector
From the suppressor, the eluent stream is routed on to the detector
(see Figure 3). The connection is made using a PEEK coupling. Pro-
ceed as follows:
1 Fit the PEEK coupling 54
Connect the "suppressor outlet capillary for eluent ("Detector")"
38 via the PEEK coupling 54 (see Section 2.3.2) to the "inlet ca-
pillary to detector block" 39.
2.6.6 Connection detector → suppressor
Downstream of the detector, the eluent flow is routed back into the
suppressor. It rinses the suppressor there after its regeneration phase.
A filter unit PEEK is fitted between detector and suppressor. Proceed as
follows:
1 Fit the filter unit PEEK
Connect the "outlet capillary from detector block" 41 via the filter
unit PEEK 54 (see Section 2.3.3) to the "suppressor inlet capil-
lary for eluent ("H2O")" 42.
