Hi everyone,

I am using online GC for analyzing permanent gas mixture of CO2,CO and O2

GC-Specifications-Two six port valves for online sampling and column switching-Hayesep and molecular sieve columns-oven temp 60 C- flow rate 10ml/min-sample loop volume 250 microL.

in my experiments i am subjecting CO2 dissociate to CO and O2. during my experiments and calibration whether same volume of gases occupied in loop, because i found out my temperature of treated sample increase by 10 C above calibration gas temperature. Also my treated products doesn't add up to 100% ,around 85% only am getting.

how to solve the issue of getting same amount of sample?
