2.15 CD Conductivity Detector
One or two ICS-3000 Conductivity Detectors (CDs) can be installed in the DC.
Each CD consists of a heated conductivity cell and the electronics required for
collecting the conductivity data and sending it to the computer and the analog
output (if installed). A suppressor (optional) can be installed on the clips on the
lower part of the CD. The cell and suppressor are installed in the upper
compartment of the DC (see
Figure 2-13 ). The detector electronics are not
accessible to the user.
2.15.1 Heated Conductivity Cell
The DC flow-through conductivity cell measures the electrical
conductance of analyte ions as they pass through the cell. Two passivated
316 stainless steel electrodes are permanently sealed into the PEEK cell
body. The cell design provides efficient sweep-out, low volume (<1
μ L),
and low dispersion. Temperature control and compensation help ensure
good peak reproducibility and baseline stability.
