"AgGC:Invalid Injection Volume" or "GC_backErrMessage" followed by "Instrument failure" errors with Agilent GC using Empower - WKB79487

SYMPTOMS

If HS is configured as front and ALS as back, while running HS, the error message shows as "GC_backErrMessage" followed by instrument failure in middle of the sample set

or

If ALS is configured as front and HS as back, while running ALS, the error message shows as "Invalid Injection Volume, Requested 1 µL does not match loop volume of 1000 µL" followed by instrument failure in middle of the sample set

or

If ALS is configured as front and HS as back, while running HS, the error message shows as "Invalid Injection Volume, 1000 μL is an invalid volume. Use 0.1, 0.2,…, 4.9, or 5 μL" followed by instrument failure in middle of the sample set

ENVIRONMENT

• ICF 3.1 and 3.2
• Empower 3
• Agilent 7890 GC
• Agilent 6890 GC
• Agilent G1888 Headspace
• Agilent 7697 Headspace

CAUSE

Reported as CRI-1009

Because all Instruments are running in the same process, two instruments can interfere with each other when the SetupMethod call of a second instrument comes in between the SetupMethod and the ValidateInjectionVolume or SetInjectionInfo call of the first instrument.

FIX or WORKAROUND

Corrected in Agilent ICF 3.3 support layer
