Stuck Capillary in Multi Purpose Valve
Shortcutting the inline filter by directly connecting its right capillary to valve port 5 can
damage the Multi Purpose Valve.
The size/position of this capillary in its fitting is incompatible, so it may get stuck
irreversibly to the valve.
âž” Do not shortcut the filter by directly connecting its right capillary to valve port 5 in
case the inline filter cannot or shall not be used.
âž” Use Capillary ST 0.17 x 120 mm, SLV/SV (5067-5416) instead.
The inline filter can be cleaned using the back-flush function in the user interface of your
Agilent instrument control software.
