The sequence has run, but I get the error message 'no signals loaded' in Chemstation. Also, the log shows, CP Macros: Data not available:Data analysis not done. Can someone please help me understand this issue and possibly solve it?
What are your detector method parameters? Basically you haven't acquired any signal data. Do you see the red vertical line when your run starts? What version of software are you running?
Thank you for the reply. I did see the chromatograms in real time, during the run. However, the method was not set up to collect signal data (detector method parameters) as you said. So 'no signals loaded'.
I am currently having similar issues as the user above. I took a picture of the run at the end (see below). The red line at the time of injection is present, but I also get the "No signals loaded" message when I try to open the run in ChemStation. While the signals are set to acquire in the MWD method, there are no .ch files in the single run folder associated with this particular run. Is there something I'm missing?
The method used was copied and modified from one that I know worked and that I could visualize later in ChemStation. Usually, the run would stop automatically at the end of the set time for the method (45.00/45.00), but in this case, I had to stop it manually in the Instrument Control Panel. Could that have been the issue?
I'll also attach a screenshot of the log file, which could help identify what went wrong.
What you might also consider doing is going into Windows Explorer (a.k.a. File Explorer in Windows 10) and navigating to the location of the files for which you're seeing the error message you stated. The typical location for ChemStation C.01.07 and earlier is C:\Chem32\1\Data\[your subdirectory or data result set folder]. The data "files" are really folders in ChemStation and they all have the extension .D. If you go into one of these folders corresponding with a datafile that has the problem, do you see any files with the extension .CH? This would be your signal file and its absence would indicate the signal wasn't collected at all.
