My conditions for methane analysis are
GC-2010/ Flame Ionizing Detector
Column Temp: Isolthermal 80 ºC
Injection: 200 ºC
Detecter: 200 ºC
He, N2, air zero and H2
When GC is ready for analysis, I inject my sample (methane gas) into injection port and then press "start". Normally (when I tested for agricultural chemical dissloved in solvent like haxane), its status will turn to "acquired" until stop time is reached.
But in this case, when I inject my sample gas, its status turns to "not ready" , "run" and then "acquired", repectively and remain "acquired" until injection has done.
I don't think it's normal but I don't know why it turns to be like this and how to fix this problem.
Please give me some advices!!!!!!
