I have a 7820A GC connected to a 5977B MS. When I submit a sample, it injects and runs as normal at first. Near the end of the run, an error message pops up that reads "Attempt to download method to GC failed." Additionally, when I check the logbook,…
Hi everybody, firstly, excuse me for my english. Please I need a video about how to install AJS and MMI in qtofms 6545, because we have a tune problem when we use MMI, (tune failed). To autotune the system, we need to remove MMI and install AJS. Any suggestions…
Hi all,
I have been trying to change our 8890 GC carrier gas with a FID from helium to nitrogen. To verify the change went well I first prepared a test mixture of lab solvents (methanol, acetone, pentane, dcm, isopropanol), ran it using He, then ran…
Hi Ive got a Varian 979 leak tester, however after a few runs the fine leak test does not work. If I use "Read standard Leak" then after it fails to switch on fine leak test. Can you please point me in the correct direction. Thanks John
Hello,
From the error code this look like error 5 with red light 2 and 4 on. Axis movement failed. Either something is blocking the X movement or there is a problem with the sensor. This will require repair. Please call the response center to get…
What likely happened is the wavelength check that is done after lamp ignition failed. When the lamp is switched on, the detector waits 1 minute to warm-up the lamp. Then a check of the deuterium emission line via the reference diode is performed. If the…
Hello pathagun ,
First thing you can double check is if any bubbles are present in the solvent lines between the solvent bottles and the degasser or the pump. You can also check if the solvent inlet filters in the bottles are blocked as these can…
Hi Sean...I think I've touched that particular instrument a long time ago. Gary - 50% 28 and 13% 32 after 24 hours is quite a big leak, maybe not massive but certainly needs fixing.
If the system worked fine before it was cooled off for a power fail…
Most likely the octopole PCA is failing. You could try dipping it, but if it happens again after redipping the board is failing and needs to be replaced.
Hello, I have a Agilient CP7420 column connected to the GCMS-QP2020NX also equipped with a FID detector and the column is connected to the FID (carrier gas helium 1mm/min). The column and the chromatograph are new, but the column was purchased from 3…
