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…
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…
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…
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?
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.

Hi Everyone,
Due to random readings of my samples, i ran wavelength and photometric accuracy test. Both of them fails, do i need to replace the lamp or is it because of the wavelength drive gear?
thanks.
