I am running GC 6890 (FID detector) alongside G1888 headspace.
I had noticed 4 of my later eluting peaks got increasingly worse in terms of shape and reproducibility. After running blanks (no injection and also blank vials), it seemed like the cause…
Hello Community,
I have been noticing random peaks, made from 1-2 data point(s), appearing in my samples where nothing should come out.
In the image below, the first chromatogram is the way it's supposed to be while the others show the mentioned peaks…
Hello!
Hoping that everyone is very well, I wanted to know if they can help me, from one day to the next the software stopped responding and asked me in the first instance for a user and password. Letting the software in and just letting a single sample…
Good Morning, Just setup a 7890B GC with Empower 3 for the CDS Built an instrument method to use both the front and back injection ports. I have a 6890N with front and back FID that we run a lot of samples on so this isn't a new method development. +…
What was the EM Voltage before the source cleaning and filament replacement? How old is the electron multiplier? They do not typically fail, the tune EMV setting slowly gets higher and higher. They typically work fine up to ~2500V or so and then the gain…

Hello! I realize this is an old post but wanted to provide more details in case other users encounter the "Make directory failed" error in the future.
This is captured in Software Status Bulletins (SSB's) in a few places.
The solution, if you encounter…
Yes, the peaks are changed at every time in response, and may be a little shifted in retention time, but Ii tried to make autotune , but it failed , so Any suggestions
Hello, I am looking at flavor compounds on a GC/FID. All of my peaks integrate really well except the aldehydes. There is a slight baseline rise long before the actual peak somes out and the GC begins integration at that time. I've tried changing the…
Hi emilymorin ,
I'm glad you found a solution that works for your data sets. I have continued to investigate this issue, but your solution does not work for all of the data sets I have tested with. I suspect disabling the save file feature may work…
