I’m sorry for the delayed reply to your message. Do you still need assistance with this? If you do, please take into consideration the notes below. However, if the issue was resolved, could you please share what the resolution was…
Hello,
I have a question about our GC 8860, which has been experiencing some problems since I changed the valve pressure.
Although it works well immediately after the change, if I don't use the GC for a few days, the first few runs produce larger…
azrael, please, for future communication, as this will save us all time! in in initial/first mail: what exactly is the HW? (here it would be GC 7890, FID EPC ...) For efficient problem solving, the REAL problem should be named. If there is also a specific…
Hi all,
I have been trying to change our 8890 GC carrier gas with a FID from helium to nitrogen. To verify the change went well I first prepared a test mixture of lab solvents (methanol, acetone, pentane, dcm, isopropanol), ran it using He, then ran…
Problem is not fid...It's PCM A flow problem..When PCM going shutdown then GC also going shut down..
Check PCM A flow path including column connected with PCM A for leak..
Hi megaflorch, The only suggestion I have on the acquisition portion of this method is that your gas save time is very short and may actually interfere with the sample if it hasn't made it on column. You have 0.75 minutes, I would lengthen out to 2 minutes…
Good morning,
We have an Agilent 7820A GC-FID equipped with a G4567A autosampler.
In the middle of a sequence, the system gave the following errors:
ALS Failure State: Preparing Samples
ALS Failure Code 945 : Autoinjector back tower plunger…
Hello lperry ,
The document below explains what that error is, essentially it could be that an ALS is not ready for injection, or some other piece of hardware connected to the GC.
