permanent gases

When using chromatography for permanent gases, is external standard analysis better or normalization? Does any master know? Please let me know. Thank you
There is no fixed pattern for this; it depends on the specifics of the analysis, the chromatography column used in the analyzer, the configuration of the detector, as well as any standard samples you have available or other methods to calibrate the analyzer. There are also many types of permanent gases, and the quantitative method to be used in the analysis process depends on the specific circumstances.
