What is Syringe and Column Adsorption of Tertiary Amines in Gas Chromatography about?
Syringe 2nd column adsorption of&5=Gary amines in gas ehrornatogaphy A modified solvent flush injection techuique has heen used previously1 to miuimk adsorption Iosses in the electroncapture gas chromatography (GC) of tertiary am&s.

Further experiments with this method of inactivation show that it has au effect on adsorption losses in the injection syringe as well as on the recovery from the gas chromarograph.
