882 Compact IC plus – Anion
If the rotor is correctly inserted, its sealing surface will be approx.
￭
4 mm within the housing. If this is not the case, the rotor must be
moved into the right position from below using a sharp object.
5 Cleaning the new connecting piece
Clean the surface of the new connecting piece (36-2) with etha-
￭
nol using a lint-free cloth.
6 Inserting the new connecting piece
Insert the connecting piece (36-2) into the housing (36-4) in such
￭
a way that the connector 1 is on top and the three pins of the
connecting piece fit into the corresponding recesses on the hous-
ing.
Reattach the union nut (36-1) onto the coupling and tighten by
￭
hand..
7 Connecting and conditioning the suppressor
Reconnect all capillaries of the suppressor to the IC system.
￭
Before switching the suppressor over for the first time, rinse the
￭
three suppressor units with solution for 5 minutes.
Which analysis quality can be attained, depends to a great extent on the
separating efficiency of the separation column used. The separating effi-
ciency of the selected separation column must be sufficient for the analy-
sis problems present. If difficulties occur, you should always first check the
quality of the separation column by recording a standard chromatogram.
You can find detailed information on the separation columns available
from Metrohm in the leaflet provided along with your separation column,
in the Metrohm IC-Column Program (available via your Metrohm
agent) or in the Internet at
Ion chromatography. You can request free information on special IC appli-
cations in the corresponding "Application Bulletins" or "Application
Notes", which are available in the Internet at
in the Applications area or via the Metrohm agent responsible.
