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.
➔ 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.
➔ 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.
