Hi dhanong, If you have 10 GC at 2 fids per GC all on at the same time using 40ml/min of H2, thats only 0.8litres per minute. I am not sure what the max would be, but I have seen that many GC on 1/8th inch line. The tricky part is when you get to the…
My cary 5000 UV-VIS-NIR shows Error code 9:9339SEQ NIR wavelength calibration failed and 9:9303SEQ Unable to initialize the instrument. What is wrong with this machine and how could I fix the problem. Thanks a lot for your advice in advance. MK
I have a simple syntax question (I think). I am trying to get the statement below to work, but am having a problem with the syntax at the Select statement. Any advice would be great: I tried this and it is failing at " x. GetCustomField ( "Sample Weight…
Hi all, I'll contribute to this topic with a few comments. I'm in no way a GC expert but I have been working with a GC-MS, basically on my own, for about a year now and I have been trying to gain knowledge on how to best operate the machine. Please correct…
Hi, we are currently unable to get Helium. We'll run our Helium gas inventory in a few weeks. Between other applications for our facility, it is used as a carrier gas on our GCs for solvent analysis (validated method). I'm copying our method below. Would…

Hi James, Just a followup on this. I changed the Lan adapter with G1530-62010. However, I still had a deconnexion this weekend and when sending a ping to the GC, the response time is random and high (between 1ms to sometimes 32ms). Is there anything else…
I have been working on an old VWD that was not used much. After running the intensity it failed only on the minimum with a 400 of >6400 cts. So more water was flushed through it over night and the same fail reoccurred. Rebuilt the cell using the g1314…
It is really rare that the transferline itself fails. It's a brazement attached to the MS with three bolts and an O ring seal. The transferline column nut threads get messed up if the column nut is overtightened. Using a 10x32 die to clean the threads…
Hi all, The GC in my lab is Agilent 7820A that my supervisor bought it 2-3 years ago. The configuration of GC is as follows: - One detector FID - One inlet Split/Splitless - One line for gas sample and One gas sampling valve. However, I am not sure there…
