Hi,
I'm having some persistent calibration issues for an ICP-OES analyzing Al, Ca, Fe, K, Na, Ni, P, Si, V & Zn in the range of 0.05 - 1 ug/mL.
The following lines (Al 237.312, Si 185.005 and Na 589.592 nm) keep failing the calibrations due to lowered…
Hello community, I set up an Agilent 6890 (Software: ChemStation A08.03). A few seconds after I start the GC, the error message "Shutdown ( # 6 ): Back Inlet Flow Shutdown" is shown on the display. The settings of the Back Inlet shows that the pressure…
Hi all We are using GC6890N in our lab to analyze dry gas, the GC with TCD and FID and four columns Two weeks ago We noticed something strange in the results like a cycle. N2 value it goes up and then goes back down. Is there any advice to solve this…
Hello everyone!
Which one do you prefer in 2019, Openlab CDS Chemstation edition or Openlab CDS-2 and why, some standard list of pros and cons maybe?
The 7890B instrument has 2 FIDs, two capillary columns in the same oven, each column connected to…
When running hydrogen carrier your source should not need as much physical cleaning (compared to helium carrier) because the H2 has a scrubbing effect. So far I've been told that there is no physical cleaning on the HydroInert source as it could damage…
Can anyone explain the negative dips in the MS TIC and why they are perfectly aligned with the spikes in the FID? Is there any troubleshooting that I can do to relieve this problem? thank you

Hi everyone! Please help me to fix the problem. I have been using Agilent 6470A.
What could be the reason for the error on the pics? MS1 and MS2 «RFPA functionality Failed». It appears everytime when I’m doing QQQ Power On Diagnostic.
Hi All.
I've installed many time Openlab from version 2.0 to 2.5 but this is the first time I get this error on a new computer that IT gave us.
Trying to install Openlab 2.5 Workstation on Win10.
It fails at the "Openlab Chemstation Access" step…
Hi everyone,
We have detected fails in 3 FLD modules installed in the same instrument.
The fist of these gave the error 06712 (emission motor did not find position),and was replaced with a second module. This when it was being installed failed again…
