Hi there, I noticed recently that the ECD back signal on Agilent GC 7890 (using it for trace gas analysis) is oddly spiking (while the FID is a straight, consistent line). It never used to do this. I just recently changed the inlet septum, could this…
I have Software Leak Test Data Wizard for VS Series Leak Detectors, but have problem to reinstall because folder Data was corrupted the file data.cab missing. Failed to install. Can anyone help without need to buy new CD Software ? withou need to buy…
It's OK.
I don't know if the valve is included in the pump or somewhere else.
If the valve fails, we'll have to use our Agilent maintenance/repair contract to clean the system... ;)
Hello, I would appreciate any help possible with this question. I have an Ultivo LC/TQ and it is having the problem with autotuning. It fails due to spray stability. Due to this I am thinking it might be the nebulizer? I take it out and see good spray;…
My Agilent 5110v ICP-OES returns an error message "Timeout in plasma controller state operations (State 7)" or "ErrorNumber_PLASMA_CTRL_BASE_STATE_TIMEOUT" and the plasma fails to lit. Please, what how do I fix the error? I have cleaned the torch, and…
Hello, Software: OpenLab Chemstation edition C.01.09 Software driver version: B.01.07.3[6648] Instrument: GC 7890B, Headspace 7697A I am using the above instrumentation and software. When I attempt to create a sequence/edit sequence table, I get the following…
I have a gas-phase reactor system that uses the FID of a 7980A to analyze the product mixture. Currently, I have a pressure buildup (up to 30 psi - the carrier gas delivery pressure) when the system is stationary. When the gas sampling valve actuates…
Hello,
we are using a G1312B binary pump (1260 Infinity) and had the error message: Fan Failed
After acknowledging the error message I can turn on the module as usual and it is working quite fine.
Nonetheless, I am not sure whether the fan is working…
I have a 6890N GC with dual FID. The back column has a much higher flow rate than the front column. The two columns are identical and the setup for inlet, column and detector are identical. I have also swapped the EPC's between the two detectors. Seems…
