Dear ALL
Hope fully you will be good and enjoying your life ,here I want to discuss one issue with you I have run three different Air samples on GC.
After analysis I found same results but Retention time ,area, height and area % was different for all samples .
Theoretical the results should also be different .
The data is as fallows ,kindly give your technical comments .
Name Retention Time Concentration Area Height Unit Area %
O2 1.233 19.6300 1235664 148553 Mole % 10.570 %
N2 1.480 79.7600 4924708 340593 Mole % 42.127%
O2 1.238 19.6300 1272611 151306 Mole % 12.154%
N2 1.485 79.7600 5084022 344817 Mole % 48.554%
O2 1.233 19.6300 1229228 147829 Mole % 15.235%
N2 1.481 79.7600 4897371 339362 Mole % 60.696%
Your prompt reply will be highly appreciated.

Three different samples, three different results, retention times the same at the second decimal. I don't see a problem.
