7.4 Routine and Preventive Maintenance
Optimum device performance, maximum uptime of the device, and
accurate results can be obtained only if the device is in good condition
and properly maintained.
7.4.1 Maintenance Plan
Perform the maintenance procedures in the table on a regular basis. The
frequency given in the table is a suggestion. The optimum frequency for
maintenance depends on several factors, such as the types and amounts
of samples and solvents used with the device.
Frequency What you should do...
Daily • Inspect the flow connections for signs of leakage or
blockage. Blockage can be determined by checking the
system pressure for unusual values or for increased
backpressure.
• When you use buffers or salt solutions, flush the device
thoroughly after use with an appropriate solvent that
does not contain buffers or salts. Monitor the
backpressure that the flow cell is exposed to.
Regularly • Inspect the flow connections for damage, such as cracks,
nicks, cuts, or blockage.
• Check the age of the lamps.
• Check that all warning labels are still present on the
device and clearly legible. If they are not, contact Thermo
Fisher Scientific for replacement.
Annually • Have Thermo Fisher Scientific service personnel perform
preventive maintenance once a year.
• Perform detector-specific Operational Qualification (OQ)
and Performance Qualification (PQ) tests.
TIP The Chromeleon software supports functions for estimating the
lifetime of consumables (see Predictive Performance ( } page 121) ).
7.4.2 Cleaning or Decontaminating the Device
Cleaning and decontamination must be performed by qualified
personnel wearing suitable personal protective equipment. Always
observe national and local regulations.
NOTICE
Wipe up all liquids spilled onto the system immediately. If surfaces are
exposed for longer periods, these liquids can cause damage.
