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…
I am having trouble separating methyl methacrylate (MMA) from another peak. The interfering compound, appearing in the front, is identified by library as 3,3-dimethyl-2-butanone and it is inherent to the sample. MMA appears as the split/tailing peak.…
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…
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…
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
Hello, thanks, we are using the version A.04.09 Agilent OpenLAB CDS. And yes, RSDRtDimethyl ist the optional variable Name from the Summary Calculations (RSD from Retention Time). The RSD (from Summary Calc) Format is a Number with 3 Decimal Places. I…
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…
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…
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…
