Hello,
I have a question about our GC 8860, which has been experiencing some problems since I changed the valve pressure.
Although it works well immediately after the change, if I don't use the GC for a few days, the first few runs produce larger…
Hello, Our lab has a GC-MS (7890B/5977B) system which uses MassHunter version B.07.01 SP1. We recently installed a FID on the system to run FID analysis separate from the MS. We are finding that MassHunter is not as suitable to use for FID analysis in…
I have an agilent GC-FID 6890 i use for TPH and PAH of soil samples yet i want to calibrate it for Oxygenates in gasoline and Aromatics don't know how to go about it
If you receive an onscreen notification to contact Agilent for your service or support request, please do so. Some instruments cannot have service tickets generated through the CrossLab Connect software.

Hi joonseok
Put the samples in a separate sequence to the wash runs. In the sequence parameters for the samples, select the post sequence option to switch off the lamps. Run the sample sequence and queue up the wash sequence from the Run control menu…
The mass calibration/check for the quadrupole is failing across all isolation widths. Mass delta on 322m/z exceeds limits.
We system tuned a few weeks ago. Can someone please outline the troubleshooting workflow for this type of issue (where to start…
Hi All, I need help to fix either baseline drifted down or change volume injection of water samples in GC/FID. Specifically, I am setting up a new GC instrument for analysis of methanol and alcohols in water samples with the following conditions: - Instrument…
Hi all,
I have been trying to change our 8890 GC carrier gas with a FID from helium to nitrogen. To verify the change went well I first prepared a test mixture of lab solvents (methanol, acetone, pentane, dcm, isopropanol), ran it using He, then ran…
A follow up question about this, if it ever occurs again. When the instrument errored out it prevented us from even initializing the instrument properly. Is it possible to auto reference even if the unit failed to initialize correctly?
Hi Paul,
Thanks for the response. We are using Agilent 5183-4702 liner, HP-5ms Ultra Inert Columns (Part Number:19091S-433UI, 30 m, 0.25 mm, 0.25 µm, 7 inch cage).
We are running in Scan, absolute. I always use autotune, I didn't find a place to choose…
