EMF Counters for Autosamplers
The GC provides access to the counters for the autosampler.
The functionality for ALS counters depends on the ALS
model and firmware version. In all cases, the 7890B GC
shows EMF counter status and allows you to enable, disable,
and clear the counters using the GC keyboard.
Counters for 7693A and 7650 ALS with EMF-enabled firmware
If using an Agilent 7693 injector with firmware version
G4513A.10.8 (or higher), or a 7650 injector with firmware
version G4567A.10.2 (or higher), each injector independently
tracks its EMF counters.
The injector counters will increment as long as the
injector is used on any 7890 Series GC. You can change
positions on the same GC or install the injector on a
different GC without losing the current ALS counter data.
The ALS will report an exceeded limit only when
mounted on a 7890B GC.
Counters for ALS with earlier firmware
If using a 7693 or 7650 injector with earlier firmware, or if
using another injector model (for example 7683B), the GC
tracks the counters for that injector. The GC uses the
injector serial number to distinguish between installed
injectors, but only maintains up to two sets of counters—one
for the front injector, and one for the back injector.
The GC will track injector counters regardless of installed
position (front or back inlet). Because the GC tracks the
injector serial number, you can change the injector
position without losing the counters as long as the
injector remains installed on the GC.
Each time the GC detects a new injector (different model
or different serial number), the GC resets the ALS
counters in the new injector’s position.
