We recently switched to MH 12.1 for our 6495C. This version of acquisition does not have tune context. Instead the autotune is in the TQ tab of the method.
When I request tune control, it does not change the TQ parameters. It only changes the temps…
The Signal-to-Noise function is better to work with printer, since there are more information on the print out than on screen, virtual printer will also do the job, When you started the function there will be guidance at the bottom of the window, it will…
Hi all,
I have a 6890A GC with a FID. We recently acquired the instrument and I have been running standards up to test methods. I have been getting signals that seem suspiciously low.
I am injecting Matreya Bacterial CP FAME mix (C11-C20 methyl esters…
We have a GCMS(5975C, intert EI source) which had been out of order since long 6 months due to ALS tray issue. After we installed tray, we cleaned ion source, replaced filaments, cleaned inlet, vent line and replaced split vent trap cartridge. Then tune…
Hi Mohammad, Thanks for your thought, detector temperature is not extremely high or low. I did monitor temperature for FID and inlet the whole time even during the injection. It was stable and maintained for hours/days. Method that I was using I had checked…
Hello everyone,
I have a 8890 GC-FID that I've just started running.
I want to create a "shut down" method that turns off (or lowers) H2 and Air once a run is completed or that can uploaded at the end of the day. The goal here is to keep the instrument…
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 guys, I'm experiencing regular times ghost peaks starting at 120°C to 295°C.....my setup is GC-FID 6890, Low pressure drop, Ultra Inert Liner with glass wool, column HP1 widebore..... I have cutted the inj/det 5 inches of column, heated at 295°C with…
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…
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…
