5.15 Conductivity detector
5.15.1 Maintenance
Caution
The conductivity detector must not be opened!
Warning
When rinsing the detector, the pressure must not exceed 5 MPa. In
order to ensure this, the maximum pressure of the high pressure pump
must be set to 5 MPa in MagIC Net.
If the conductivity detector is blocked, you should first of all check
whether the blockage results from the capillary ends being pressed
together too firmly. In this case, shorten the detector input capillary (40-3)
or the detector output capillary (41-2) by several millimeters.
If this does not help, the conductivity detector can be rinsed against the
normal flow direction. For this, connect the high pressure pump to the
detector output capillary (41-2) and rinse - the pressure may not
exceed 5 MPa.
5.16 Separation column
5.16.1 Separating efficiency
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 information sheet provided along with your separa-
tion column, in the Metrohm IC-Column Program (available via your
Metrohm agent) or in the Internet at
http://www.metrohm.com in the
product area Ion chromatography. You can request free information on
special IC applications in the corresponding "Application Bulletins" or
"Application Notes", which are available in the Internet at
http://
www.metrohm.com in the Applications area or via the Metrohm agent
responsible.
