Conditioning the dialysis system
Prior to the first analysis, the dialysis cell with dialysis membrane in place
and all capillaries must be rinsed with ultrapure water.
1 Setting the injection valve
Set the injection valve to the
FILL
position in the software.
2 Putting both peristaltic pumps into operation
￭
Immerse the aspiration capillary in the acceptor solution
(degassed ultrapure water).
￭
Use the software to switch on both peristaltic pumps.
￭
Adjust the contact pressure on both peristaltic pumps
(see the
chapter "Installing the peristaltic pump" in the manual for the
ion chromatograph or the Sample Processor)
.
3 Conditioning the dialysis system
￭
Rinse the dialysis system with ultrapure water for 20 min.
￭
Check whether equal amounts of solution are emerging from
both feed lines to the waste container.
￭
Check whether all capillary connections are tight.
If liquid is escaping somewhere, then tighten the corresponding
connection or redo the connection.
￭
Check whether any air bubbles remain trapped in the dialysis cell.
If air bubbles are trapped in the cell, then unscrew the PEEK capil-
lary and the PTFE capillary,
, from the outlets of the
dialysis cell and wait until the air bubbles have escaped. After-
wards, tighten the capillaries to the dialysis cell again.
