Hello,
We have an agilent 6545. Today when we are doing a mass calibration check, the masses of the negative tune ions seems to be shifted (For example 1633.9988 is now showing 1639.2109 and so on for the other ions) and mass calibration check seems…
Hi I have a very basic question, please correct me if I am wrong. I am using GC 7820 with FID detector. Flow , Pressure everything was set by another technician before I started. I know for Back Detector everything is what is set by the Technician in…
Hi,
Our QTOF system failed to do a polarity switch from positive to negative. But it works fine at the positive mode. Just wondering if anybody knows the problem. Here is the instrument log record:

Actually, you have to be sure that it's detector problem or not.
And if still problem persist and after changing lamps intensity test, wavelength test failed again then you have to call to your local agilent support to check electronics and optics etc…
As long as you do not see any issues in your measurements, you can keep using the EM, until your new EM has arrived. At some point the Pulse HV will reach ~1800 V and the Analog HV will reach ~ 3300 V (if you are lucky). After that you will have to replace…
Hi, I am using Agilent 7820A GC-FID with EZChrom Elite v3.3.2. software. After the completion of each sequence, I would like to automatically generate a .text file along .dat file. So far, after the sequence has ended, I process the sequence and then…
Hello, my friend, After checking the logbook on the ChemStation, note that the method did not run due to an error in the G4212B detector indicating: Start Failed (temperature HW). After that, I checked the instrument with the Lab Advisor, and the Logbook…
Hello,
The RI uses a lamp and since it's works on refractive index differences, it doesn't use a wavelength. The RI is what is called a "bulk" detector.
If you are thinking you can replace the lamp, it's part of the optical unit and when it fails…
Hello team, I wanted to consult the following: an HPLC 1260, I had to reinstall the software. Once I did it, after creating a new method and giving the order to inject, the software turns blue and immediately turns green and does not inject... After checking…
Good Evening, I realize this is a bizzare question but basically what we have is a Dean Switch GCMS system and we use cut windows to determine when the best time is to switch from column 1 (inlet to switch to 3rd column - vent) to column 2 (inlet column…
