Can you let us know what software you are using? Perhaps provide an example of what you are seeing?
Hi James .....
thank u for you'r response and I'll send u in sunday all informations abut the software that I work on it
The software that I use is ( shem station software ) and when the analysis began run ther is no line drawn
on the chromotegam secreen
Can you support us with more information about the type of detector and the parameter for detector and method,
and example for screen.
Thank you for you'r response
The detector is FID detector and the parameter is the routine heating method
is the base line from chromatogram disappear before you inject the sample or after you press start button?
Thank u for you'r answer
before and after there is no line
Can you give a screenshot while it is running?
Iwill do it as soon as i fixed the problem with my software
The main reason for this problem you didn't select detector signals.
when we don't selecAdd t signal detector we never see baseline chromatogram,to solve this problem from online plot for FID signal Click on change than from Edit signal plot remove FID signal from Available signals(left side) to selected signals( right side) by Click on Add than Click on Ok. like blow image.
I hope this help you to solve the problem.
