Regenerating the Metrohm Suppressor Module (MSM)
Regenerate the three suppressor units one after the other for approx.
15 minutes using one of the solutions mentioned above.
￭ Connect the capillary labeled regenerant to the outlet of the
high-pressure pump using a coupling (6.2744.040).
￭ Set the flow of the high-pressure pump to 0.5 mL/min in the soft-
ware.
￭ Connect the regeneration solution to the high-pressure pump.
￭ Switch on the high-pressure pump.
If the pressure decreases during regeneration, slowly increase the
flow of the pump to a maximum of 2 mL/min. When doing so,
make sure that the pressure does not exceed 2 MPa!
￭ After approx. 15 minutes, switch off the high-pressure pump.
￭ In the software, use the Step command to switch to the next
suppressor unit and regenerate it as described above.
￭ As soon as all three suppressor units have been regenerated, dis-
connect the capillary labeled regenerant from the coupling.
3
Rinsing the Metrohm Suppressor Module (MSM)
After regeneration, each of the three suppressor units must be rinsed
with degassed ultrapure water for about 15 minutes.
￭ Connect the capillary labeled rinsing solution to the outlet of
the high-pressure pump using a coupling (6.2744.040).
￭ Set the flow of the high-pressure pump to 0.5 mL/min in the soft-
ware.
￭ Connect the ultrapure water to the high-pressure pump.
￭ Switch on the high-pressure pump.
If the pressure decreases during rinsing, slowly increase the flow
of the pump to a maximum of 2 mL/min. When doing so, make
sure that the pressure does not exceed 2 MPa!
￭ After approx. 15 minutes, switch off the high-pressure pump.
￭ In the software, use the Step command to switch to the next
suppressor unit and rinse it as described above.
￭ As soon as all three suppressor units have been rinsed, disconnect
the capillary labeled rinsing solution from the coupling.
4
Connecting the Metrohm Suppressor Module (MSM) to the
IC system
￭ Reconnect the capillaries of the MSM labeled regenerant and
rinsing solution to the IC system.
￭ Reconnect the entry and the exit of the high-pressure pump to
the IC system.
