Detector temperature low when start a new run

Question

As the auto trail log, instrument is not able to maintain the temperature between injection. It seems like the temperature and gas flow will drop at the beginning of the run. 
 I have checked the leakage from detector/inlet/column but nothing found. Please advise if you have any suggestion to clear this during the run.

Hi Mohammad, Thanks for your thought, detector temperature is not extremely high or low. I did monitor temperature for FID and inlet the whole time even during the injection. It was stable and maintained for hours/days. Method that I was using I had checked it and reviewed without any noticeable errors, and I was using the method for months. After I switch to a new column the problem solved. I took out the column and noticed that there is a gap between my packed column. I think the main issue the column that I used turns bad or need to fill up more packing material to able perform this method without any warnings.
