We have a Duo 2.5 foreline pump that was replaced in June of this year (2023). The previous Duo 2.5 installed had a sudden catastrophic leak, thus the replacement in June. The oil was filled up halfway and I set a marker with tape to monitor the level…
Hi John, You are on the right track-- it sounds like your flame is not lit. The reading you are seeing on the Hydrogen line is likely back-pressure from the column flow. That result could indicate a blockage in the jet, but the flow is a little low to…
no you don't need to disconnect it from the FID, ,
bake the column for enough time usually more than 1 hour according to your column status , you can keep the FID working to monitor the baseline .
..
keep temperature 25 degrees less than the maximum…
Hi all, I am using a GC 6890 with split/splitless inlet to analyse reaction products. However, a problem has recently happened when the GC is running. I have noticed the appearance of spikes in the baseline of the FID detector. The spikes appear occasionally…
It looks like it is having to clear something out the inlet, column, detector or head space as the baseline rise is over most of it. I see it's a FID you are using, how long do you leave it ignited before running the first analysis?
Hi, I have a agilent GC 7890B with FID. currently i am a facing a problem regarding this GC, problem is like that - all gases supply is ok, no leakage is found in detector portion. i have cleaned the FID & Jet but flame is not burning. So kindly suggest…
Hi byoo,
Do you get any failed to communicate or any other message when you start up the software? You are correct if the busy light should be constantly flashing. This means you got a successfuk firmware load from the PC from ethernet connection. Can…
Hi all,
I'm using a 0.18 mm HP-5 GC Column on a Shimadzu GC-2014 connected with a FID. I'm looking to get new ferrules (the old ones had been passed down from previous users) and wanted to discuss some options. I tried using some 0.5 mm graphite ferrules…
good day!
tell my please..
I have the air generator and his out pressure consist 52 psi, and and air consumption is 1000 ml/min. the EPC module GC 7890b work in rang 55-80psi. I have 2 detector FID. Tell my - with this generatorom may be worked ?…
Get a WS asynchronous error : F F60304 The torch ignition has failed when starting a Varian 720 OES The torch lights and stays on for about 5 seconds then shuts down with this error. I can not find reference in the help to resolve this. Thanks, Scott
