We have three Sulfur SCDs, two of which have inordinately high signal outputs:
1) Agilent 355; Model #G6644A; SN #CN11411006; PMT #DC7303; with FID on HP 5890 Series B
2) Sievers 355; Model SCD355; SN #0500-918; PMT #WB5942; with FID on HP 5890 Series…
The front inlet on my GC8890 is failing the restriction test. It passes the leak test no problem and I've done everything I can think of to fix it. I've replaced the septa, checked the gold seal, trimmed the column, baked the column, and checked the inlet…
Related question. Simple GC with a valco rotary valve, 10 position, 6 position, whatever. what is the scfm requirement for that pneumatic device over the course of a method run where after half a minute the valve switches, then 15 minutes later switches…
By chance is your TCD plumbed to your FID, non destructive to destructive detector configuration? Or using a splitter device of some type? A picture from inside the oven would help. Have you tried the split vent maintenance yet? I would do this even without…
Hi All, We are experiencing a very strange issue (very broad peak) with Dimethyl Formamide Solvent when run with one particular residual solvent method utilizing Dimethyl Formamide as Diluent. Method has been run for the past 4/5 years without any issues…
Hi everyone, A few weeks ago in our lab we installed a new inlet/column/detector set-up on an existing 7890B GC in our lab. This GC already had a front inlet/detector installed and there was never anything installed on the back components. Therefore we…
Hi danots, Thank you for your reply. We have tried exchanging the ceramic tubes (upper and outer) several times, but this does not do the trick. Also the columns have been replaced frequently, as we customize the application a lot being R&D. The SCD works…
I have an Agilent 5975C MSD and 7890A GC that I'm getting a failed PING test on. I've done the troubleshooting I can (reboot system in proper order, reboot PC). I can ping the main IP but the ones going to the instruments fail. Please advise. PC is running…
I have a 6890N GC-FID with a 7683 Series ALS and I'm using Agilent Open Lab (EZChrom Edition) software. The software won't trigger the autosampler to make an injection. A box appears on the screen with the message 'Incompatible Tray'. I have verified…
Hi carcuri13, This sounds like the heater sensor assy is failing. If the change is rapid in temperature , the thermal block is not capable of changing quickly. The heater sensor would need to be replaced. Regards James
