I am doing GC-RGA data for the experiments. When I am doing GC analysis online then there is too much deviation in the results from first-hour run to second-hour run. However, when I am doing the GC analysis through tedlar bags then the GC analysis is showing the same results.
Which is the better way online GC or through Tedlar bags? and why there is a deviation from the first run to the second run in the GC analysis. Any comments will be helpful.
Thanks
Online GC results typically offer greater accuracy and real-time data capture compared to sampling through Tedlar bags, which may introduce potential contamination and time lag between collection and analysis.
Online GC analysis is always recommended to minimize the error for gas analysis. However, for online GC analysis, we must ensure a constant flow rate from the reactor system.
