This procedure describes how to replace the mechanical part (the “pod”) of both the standard injection valve and the optional auxiliary valve. This procedure is usually an easier and faster alternative to rebuilding the valve (see Rebuild the injection valve or auxiliary valve).
NOTE
Service on internal electronics of the Dionex Inuvion IC System and accessories must be performed by Thermo Fisher Scientific service engineers.
