Since absolute retention times are affected by many operation parameters, retention parameters less dependent on column dimension and analysis conditions may be desired. Such parameters are expressed by the relative relation of adjustable retention time between the standard sample and unknown sample: relative retention and retention index. [email protected] Opetating Area Density %lymer TemL m21gnm gnm/cc Since the development of porous polymers for use in gas chromatography by Hollis and Hayes in the mid 's, very little has been done to improve their-performance.
