Plumbing the Amperometry Cell
Install the Dionex ED50A amperometry cell directly after the column.
Figure B-15 shows the plumbing schematic for amperometry detection.
A second detector can be installed before the amperometry cell. However,
if a second detector is installed after the cell, make sure the pressure at the
amperometry cell outlet remains below 700 kPa (100 psi). Because of the
volume within the pH reference electrode section of the cell, you may
note some band broadening at the second detector. However, this is
minimized by the precision flat bottomed pH reference electrode.
