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 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…
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…
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?
There is an SP7 switching valve on our 5110 ICP-OES The first set of triplicate aspirations of Std always ride really close to the precision limit of 2%RSD and then std#2 and Std3 are typical 0.5 or less. (ISTD Method) All of these standards are in the…
I have a 7820A GC connected to a 5977B MS. When I submit a sample, it injects and runs as normal at first. Near the end of the run, an error message pops up that reads "Attempt to download method to GC failed." Additionally, when I check the logbook,…
When the tuning is done at 3200 (+) everything is fine. When I change it to tune at 1700 (+) the masses are reasonably accurate. After it gets to the third mass (620) it appears that the entire spectrum shifts by about 1.5 AMU and the tuning fails. There…
The optional high vacuum gauge has a cable between the gauge and the electronics. It is either disconnected or the gauge has failed.
See page 125 and 126 in the 5977B Series MSD Operating Manual for instructions on how to turn it on and off.

Hello, I have a Agilient CP7420 column connected to the GCMS-QP2020NX also equipped with a FID detector and the column is connected to the FID (carrier gas helium 1mm/min). The column and the chromatograph are new, but the column was purchased from 3…
