1 Introduction
1.1 Description of the IC equipment: Dialysis
The IC equipment: Dialysis (6.5330.100) contains all accessories required
for inline dialysis of matrix-contaminated samples (e.g. emulsions, samples
containing fat and protein, body fluids or waste waters with high pollution loads) directly before injection.
The main component of the IC equipment: Dialysis is the high-performance dialysis cell. The ions travel through the semipermeable membrane,
diffusing out of the flowing sample and into the stationary acceptor solution, where they are preconcentrated. The ion-preconcentrated acceptor
solution is then subsequently injected directly into the IC system.
To operate the dialysis cell, you need an IC system with a peristaltic pump
and a cell holder as well as a Sample Processor with a peristaltic pump.

2.4 Mode of operation for dialysis
2 Overview
Figure 4 Stopped-flow dialysis
Sample is delivered continuously on the sample side of the dialysis cell.
After a rinsing phase, the acceptor flow is stopped. Because of the concentration gradient, the ions pass through the membrane. The acceptor
flow remains stationary until a concentration equilibrium is achieved
between the two cell halves. The concentration in the acceptor solution
thus matches the concentration of the original sample. Afterwards, the
acceptor solution is injected directly into the ion chromatograph.

3.4 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 capillary and the PTFE capillary, (3-3) and (3-6), from the outlets of the

4.1 Operation
4 Operation and maintenance
4.1 Operation
4.1.1 Optimizing the dialysis
Determining the rinsing time
A rinsing time of two minutes is usually sufficient for completely rinsing
the sample and the acceptor channel. If necessary, this time can be
extended.
Determining the transfer time
The time for the transfer of the preconcentrated acceptor solution into the
sample loop must be chosen in such a way that the part of the acceptor
solution with the highest ion concentration will be transferred into the
sample loop.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
The optimum transfer time should be determined for each analysis problem on the basis of measurements of the individual ion concentrations in
relation to the transfer time and periodically verified.
1
Initial measurement
￭ Set the following values in the software:
– Transfer time: 15 s
– Dialysis time: 10 min
￭ Immerse the sample aspiration capillary in a standard solution
with 10 mg/L of the desired anion or cation.
￭ Start the determination with the appropriate method in the soft-
ware and wait until the chromatogram has been evaluated.
2
Additional measurements
￭ Increase the transfer time in the software by 5 s each time and
start the determination.
￭ Repeat the measurements until the measured area starts to
decrease again.
3
Determining the optimum transfer time
￭ Record the area in relation to the transfer time and determine the
optimum transfer time.
Figure 5 exemplifies this relation.

According to this curve, the optimum transfer time is between 27
and 32 seconds.
IC equipment: Dialysis
Determining the dialysis time
After the optimum transfer time has been established, the optimum dialysis time must be determined. This time depends on the total ion concentration in the sample.
The dialysis time is the time during which the acceptor flow is stopped
and only sample is pumped. This time must be chosen in such a way that
100% of the sample concentration is achieved in the acceptor solution.
For the dialysis membrane (6.2714.010) (cellulose acetate; thickness =
115 µm; pore size = 0.2 µm) and a total ion concentration ≥ 5 mg/L in the
sample, the standard dialysis time value is 10 minutes.
This standard value must be verified for each installation.
1
Measuring the standard solution without dialysis
￭ Remove the capillary that is connected to the dialysis cell outlet
for the acceptor solution (3-6) and immerse it in a standard solution with approximately the same total ion concentration as the
sample.
￭ In the software, start a determination that measures the standard
solution directly (i.e. without dialysis).
￭ Reconnect the capillary to the dialysis cell outlet for the acceptor
solution (3-6) and rinse the acceptor channel for two minutes.
￭ In the software, stop the peristaltic pump for the acceptor chan-
nel.
￭￭￭￭￭￭￭￭
17
4.1 Operation
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
2
Measuring the standard solution with dialysis
￭ Set the dialysis time in the software to 5 minutes.
￭ Immerse the sample aspiration capillary in the standard solution
used in step 1.
￭ Start a determination in the software and wait until the chroma-
togram has been evaluated.
3
Additional measurements
￭ Increase the dialysis time in the software by 1 minute each time
and start the determination.
￭ Repeat the measurements until the measured values are stable.
4
Determining the optimum dialysis time
￭ The recovery rates can be calculated from the result without dialy-
sis and the results with dialysis. You can determine the optimum
dialysis time by recording the recovery rate in relation to the dialysis time.
4.1.2 Recommended procedure for the dialysis
For sample determination with dialysis, it is best to proceed according to
the following sequence:
Carrying out a dialysis
1
Preparing the acceptor solution
￭ To avoid disruptions caused by air bubbles in the acceptor flow,
degas the ultrapure water used as acceptor solution for at least
10 minutes.
2
Preparing the sample
￭ To avoid blockage of the sample channel, always centrifuge sam-
ples with a high content of suspended or solid particles in a tabletop centrifuge for 5 minutes at 10,000 rpm.
3
Putting the IC system into operation
￭ Switch on all required devices.
￭ Start the software and load the required IC system.
￭ Condition the IC system.

18
IC equipment: Dialysis
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
4 Operation and maintenance
4
Putting the dialysis system into operation
￭ Immerse the aspiration capillary for the acceptor solution in the
acceptor solution.
￭ Immerse the sample aspiration capillary in a rinsing solution (e.g.
ultrapure water).
￭ Start both peristaltic pumps in the software.
￭ Rinse the dialysis system with the acceptor solution and the rins-
ing solution for approx. 10 minutes and then switch off the peristaltic pumps again.
5
Calibrating the IC system
￭ Immerse the sample aspiration capillary in the standard solution.
￭ Start the determination in the software and wait until the stand-
ard chromatogram has been evaluated.
￭ Repeat the two steps for all standard solutions.
6
Determining the sample
￭ Immerse the sample aspiration capillary in the sample solution.
￭ Start the determination in the software and wait until the chroma-
togram has been evaluated.
7
Rinsing the dialysis system
￭ After the end of the measurements, immerse the sample aspira-
tion capillary in the rinsing solution.
￭ Switch on the peristaltic pump for the sample channel in the soft-
ware.
￭ Rinse the dialysis system with the acceptor solution and the rins-
ing solution for approx. 10 minutes and then switch off the peristaltic pumps again.
8
Taking the dialysis system out of operation
￭ If the dialysis cell is taken out of operation, then you have to rinse
the acceptor channel and the sample channel with ultrapure
water for approx. 10 minutes.
Then remove all four capillaries of the dialysis cell and close each
opening with a threaded stopper (6.2744.060).
￭ If the dialysis cell is taken out of operation for a longer period,
then you have to remove the dialysis membrane and clean the
dialysis cell (see Chapter 3.1, page 6).
￭ Release the contact pressure in order to relieve the pump tubings
(see the chapter "Peristaltic pump" in the manual for the Sample
Processor).
