9. Maintenance and care
9.1 General
Maintenance of a HPLC instrument is critical to the success of analyses
and the reproducibility of results. If you require a maintenance task which
is not described here, contact your dealer or the Customer Support.
All wetted components of a device, e. g. flow cells of detectors, have to
be flushed with isopropanol first and water second before being maintai-
ned, disassembled or disposed.
