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…
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 All, I need help to fix either baseline drifted down or change volume injection of water samples in GC/FID. Specifically, I am setting up a new GC instrument for analysis of methanol and alcohols in water samples with the following conditions: - Instrument…
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…
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…
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.
It was on the equipment, you can check to be sure by running a performance check on the chiller. Our chiller passed all points on the performance check but failed on the ICP system.
thanks for your answer. Regarding the ion source (EI): it happens that in a relatively new column, the abundance of the peaks of the same control that I had been injecting almost 3 weeks ago, has decreased from 5 x10^5 to almost 1x10^4. I tried injecting…
