Hi,
there is quite a big drop in sensitivity in August. that's interesting. Are the MassHunter settings for the "Configure Ignition Sequence" "Standard Tune" and are all the Startup tasks, beside the P/A factor and EM run succesfully? please run then…
Can SimDis data processing be performed manually (i.e. without the aid of additional SimDis software produced by Agilent or a third-party) with a GC running Chemstation?
I'm looking for a low-cost solution to perform SimDis analysis of jet-fuel samples…
Please try to remove the sample probe and perform the initialization. If it completes successfully make sure the probe is not touching or causing the movement issue. If it failed. Call the response center to get more help with the SPS-4. It could be a…
Hi, I have a GC/MS (8890 GC with 5977b HES MSD) that is also configured with an FID and PDHID. I would like to create an FID/PDHID-only method, where the MSD remains off the entire run and does not collect data. I haven't figured out how to do this so…
Hello Paul, it looks to me that there is too much acetylene in the gas mixture coming to the burner. This is causing the carbon build-up.
I'd suggest you first remove the absorption cell from the holder and clean this by soaking in dilute nitric acid…
I am using an Agilent 6460 Triple Quad and have been dealing with a terribly low signal for the past few days, the signal appears at an abundance of 30 to 50 as a baseline only. I analyzed different compounds with different concentrations, the Tune mix…
I am trying to run a Injector Precision PV test using the conditions described in the software: caffeine standard (125 ug/mL) and HP ODS Hypersil 5 um, 125 x 4 mm part 7982618-564 . The method uses 85:15 Water:ACN mobile phase at 0.8 mL/min. The test…
Hello mkaadan ,
What I meant by a "low" failure rate (notice the quotation marks), is that it is likely not an indication of a leak, as that would result in a lot more samples failing, or potentially all of them. By no means I wanted to minimize the…
Hi everyone. I have a problem with my 8890 GC-MS as I do not have pressure in the inlet. The issue began during the IT outage, the EPC module turned off itself hence all heated zones turned off as well. When I managed to re-establish the connection I…
