Description

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 the linearity obtained from a 5-point calibration curve (0.05-1%) for water on Watercol 1460.
