Connections to the regenerant bottle differ depending on whether the
system will run an anion or a cation application. Regenerant bottles for
each type of application are available (anion regenerant bottle assembly,
P/N 068222; cation regenerant bottle assembly, P/N 068223). For detailed
installation instructions, refer to the
DCR Kit Installation Instructions
(Document No. 031664), provided on the Dionex Reference Library CD-
ROM (P/N 053891).
2.3.6
Conductivity Cell and DS5 Detection Stabilizer
The flow-through heated conductivity cell contains two 316 stainless steel
electrodes that are permanently sealed into the PEEK cell body. The cell
measures the electrical conductance of analyte ions as they pass through
the cell.
Temperature directly affects the conductivity of a solution. For example,
laboratory heating and air conditioning systems can cause a regular slow
cycling in the baseline. This, in turn, can affect the reproducibility of an
analysis. The higher the conductivity, the more pronounced the effect.
