I am facing huge differences in area response by valve injection and manual injection of gaseous standards into GC. For the same amount, concentration and split ratio, the manual injection gave responses around 200% higher. I tried change the load time and injection time between the range of 0.5 and 1 min and didn't note any differences.
Any one has any idea that could help in this case?
