Early Maintenance Feedback (Emf); Emf Counters - Agilent Technologies G1367A Reference Manual

Early Maintenance Feedback (EMF)

Maintenance requires the exchange of components in the flow path which are
subject to mechanical wear or stress. Ideally, the frequency at which
components are exchanged should be based on the intensity of usage of the
instrument and the analytical conditions, and not on a predefined time
interval. The early maintenance feedback (EMF) feature monitors the usage of
specific components in the instrument, and provides feedback when the
user-setable limits have been exceeded. The visual feedback in the user
interface provides an indication that maintenance procedures should be
scheduled.

EMF Counters

The autosampler provides four EMF counters. Each counter increments with
autosampler use, and can be assigned a maximum limit which provides visual
feedback in the user interface when the limit is exceeded. Each counter can be
reset to zero after maintenance has been done. The well-plate sampler
provides the following EMF counters:
Injection Valve Counter
This counter counts the number of valve switching EF4512, since the last reset
of the counter.
Needle Assembly Counter
This counter counts the total number of needle into seat movements (used for
the needle life time) EF4510, since the last reset of the counter.
Seat Assembly Counter
This counter counts the total number of needle into seat movements (used for
the seat life time) EF4511, since the last reset of the counter.
Peristaltic Pump
This counter gives the accumulates active pump time in units seconds EF4513.
