Preventive maintenance inspection plan
Generally, the instrument is maintenance free, but in order to ensure a functioning K-Patents instrument, the
following preventive maintenance inspection plan is proposed. The weekly PMI plan includes only recording
of the diagnostic values without any service procedures. The annual plan includes also the verification
procedure and prism check for scaling or wear. In addition, there are some specific applications such as
aggressive solvents that require replacement of the flow cell o-ring gasket every 3 months.
