Analysis Note The "Watercol" series of ionic liquid capillary GC columns are characterized by their ability to produce a sharp peak shape for water, sharp enough so that water can be integrated and quantified. This application shows a calibration standard (0.5 mg/mL water in acetone) on Watercol 1910.
