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 Ron, cheers for that. I have made a note of that method flow, thanks, but it's looking like it may be a touch moot; I cannot find the discs anywhere. I have sent an email to our IT team to see if they have them, but otherwise I'm at a bit of a loss…
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, 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…
Resurrected a 6890 which has not been used for a while. When the chemstation is turned on, it gives message of "Limits fail: liner(injection)". Pulled out and cleaned/replaced microseal (fine), glass liner with o-ring (no physical samage) and golden seal…
Hi Nick- Thanks for that information! I'm not sure if that's the cause here. It was 8 million when it was installed in December 2015, in August 2016 it was 9 million, March 2017 it was 8 million, April 2017 was 7 million, then August 2017 it was only…
Thanks ryoboyle and dheyaaldeen . I renamed the 4 files (config.reg, ChemStationPerInstrumentSettings.config, instrument.config, RapidControl.InstrumentConfig.xml). I do not have a user.mac file in the CORE folder. The program opened once and I reconnected…
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…
megaflorch - this was fairly old topic and I wasn't sure if you completed your standards/sample prep. I use a similar technique to get my analytes within a better working linear range with respect to my GC-FID. Your logic is good.... here is my standard…
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…
