7890a Auto stop occurs after one sequence progression

JeonghoYang

Hi, everyone.

Suddenly, from yesterday, it does not automatically proceed to the next sequence after the sequence ends with a message like the picture below.

(The following parts of the Method are Not Consistent with the GC  Configuration.)

The message pops up approximately 30 minutes after the sequence starts.

If I press the resolve button, the same screen will pop up continuously, and if I press the don't resolve button, the window will no longer appear and will not automatically proceed to the next sequence.

In order to take action, we selected a method that worked normally, but the same symptoms continue to occur. 

Please give us your opinions.

Thank you.

    It looks like theres a problem with the back inlet/back autosampler -  the gc does not recognize it anymore - but it seems to be defined within the method, meaning it has a inlet temperature ect.

    Did you change something regarding the back inlet? or the back autosampler?

    Do you use the back inlet to inject the samples? Or the front inlet?

    I see 2 FID chromatograms on there, is it a system with 2 inlets where you just use the front inlet to inject and then the sample gets split (with a Y splitter) onto 2 different columns ?

    Maybe you made a mistake when setting up the sequence - you chose the correct method for the first sample and then a different method for the 2nd sample (a different method that might cause this error)?
