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 data shows the linearity obtained from a 7-point calibration curve (0.1-100%) for water on Watercol 1460.
