Hello,
I have a question about our GC 8860, which has been experiencing some problems since I changed the valve pressure.
Although it works well immediately after the change, if I don't use the GC for a few days, the first few runs produce larger…
I am currently having a flow issue with my 6890N GC(w/ G1888 HS). I am doing yearly flow checks. Hooked up a calibrated flow meter to DET exhaust and turned off all gases (pressure off, makeup He off, Air off everything). I then enabled them one at a…
Hello,
I am getting the following error on OpenLab CDS Chemstation Edition (Rev. C01.10 [287]): "User Change (Unlock) failed, because instrument access is not permitted for user. Logging Out User". We are initially able to login once, but then when…
Hello, Our lab has a GC-MS (7890B/5977B) system which uses MassHunter version B.07.01 SP1. We recently installed a FID on the system to run FID analysis separate from the MS. We are finding that MassHunter is not as suitable to use for FID analysis in…
Hi joonseok
Put the samples in a separate sequence to the wash runs. In the sequence parameters for the samples, select the post sequence option to switch off the lamps. Run the sample sequence and queue up the wash sequence from the Run control menu…
