Good day!!
I am using Perkin elmer clarus 580 model equiped with FID and TCD detector.No peaks are seen while eluting permanent gases through Shincarbon ST column connected to TCD. However previously all peaks were eluted without any problem the GC system was offline for a while(1.5 months) and after that no peaks were seen eluting from TCD.
