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;…
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... ;)
We don't know what is in your water samples, but on a CP-Wax 57 CB benzene and isopropanol are eluting very close to ethanol, just in front of it.
You can find examples of applications of alcoholic beverages on Wax 57 (all types) in Scanview ( (+) Software…
Hello mckenzie.stevens ,
Did this error occur when attempting to work with the FID data? I've not seen this exact error, but it is possible to receive similar errors when having a spectrum tool selected and trying to work with non-MS data. If you then…

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. We have a 2- dimension gc/fid/ms 8890/5977C with a masshunter software. Our aim is to quantify molecular markers (e.g. 1,3,5-Tri-tert - Butylbenzene) used in gasoil to trace fraud. For quantitation we use a sim method (Quantification sim 231 and…
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…
Hello,
Thank you for the response. I created MH_meida folder in C drive and also enabled .NET 3,5. But I received error message again after trying to install qual 10.0. Any suggestions would be much appreciated. Thank you.
here is the error log…
Hello ljones031 ,
I would suggest copying the installation files to a folder on the local hard drive and then disconnecting any external drives before attempting installation. Most MassHunter programs will try to install to a D: drive it if is found…
