Hello I have an ICP-MS 7900. My Check Performace fails all the time. I washed the entire system and replaced the chambers and cone again. The same applies to oil changes. Nevertheless, my Check Performace fails. Can anyone help me with this? Or someone…
Hello
We have an agilent ultivo qqq and last week when trying to run a checktune it failed giving a message saying calibrant bottle is empty or nebulizer is clogged. Nevertheless the calibrant bottle is definitely not empty, and the nebulizer also doesnt…
Hello, I have a G1321B that showed errors during the OQPV. The FSE changed the flash lamp Iand the Intensity test is OK arround 10000 counts buen the and Raman ASTM Signal/Noise fail. I want to know if there are another test to do.
I changed my acquisition method from using front FID to back FID. I changed this in the acquisition method detector, signals, and columns sections. On my status tab, the detector is still showing front FID and the online signals is showing no options…
Hello,
Our lab currently uses a headspace-GC-FID to analyze for ethanol in blood samples. We have a multi-level, internal standard calibration curve as well as control samples at various concentrations that are analyzed in a sequence. Is there a way…

Hello lperry ,
The document below explains what that error is, essentially it could be that an ALS is not ready for injection, or some other piece of hardware connected to the GC.
6890 GC Not Ready Messages (agilent.com) (bottom of page 9).

When doing autotune I get high precursor in mass 502. I get 12.79% and the limit is 12%. The manual says that it could be contaminated. The equipment has had preventive maintenance recently but it has now this problem. Previously it had a ratio of mass…
Hello,
I am expeirencing the same issue after having to reload E.02.02.1431. The quant report prints as one job and the chromatogram and the spectra reports (I'm printing a detailed report) print as a second job.
I've done as ron_tackett mentioned…
Hello vanphu, Thanks for the model information. On power on, the motor needs to move the pump to specified positions and if it fails to do so in a range of motor steps, it can give the error you mentioned. We advise to leave the pump stroke in auto to…
