CBM-20A/20Alite
Replacement parts for this instrument will be available for a period of seven
(7) years after the discontinuation of the product. Thereafter, such parts may
cease to be available. Note, however, that the availability of parts not
manufactured by Shimadzu shall be determined by the relevant
manufacturers.
Each LC component and the entire LC system should be checked
periodically to ensure that they function normally, or the analysis data may
not be reliable. To this end, it is necessary to carry out periodic hardware
validation and keep records of the validation. There are two types of
hardware validation - component validation and system validation. The
purpose of component validation is to check that the individual components of
the system function normally, while the system validation checks that the
system as a whole (the several components in combination) functions
normally.
Before shipment from the factory, this instrument was rigorously inspected.
The results are summarized in the Inspection certificate accompanying the
instrument. To inspect the instrument performance after installation, repeat
the Hardware Validation as described in "7 Hardware Validation".
