EMF Counters for MS Instruments
When configured to an Agilent MS that supports enhanced communications (such as a 5977
Series MSD or 7000C Triple Quadrupole MS), the GC reports the EMF counters as tracked by
the MS. The MS provides its own EMF tracking.
When connected to an earlier model MS (for example, a 5975 Series MSD or 7000B MS), the
GC tracks the MS counters, not the MS.
For GC-MS, GC-HS, and GC-MS-HS systems, all EMF counters are available at the GC
touchscreen. In addition, most counters can be reset at the GC touchscreen. Some counter
types, for example, a counter which requires a calibration to be performed on a headspace
sampler, cannot be reset at the GC touchscreen, but can still be viewed.
