• Application: Watercol capillary GC columns contain innovative ionic liquid stationary phases that produce a sharp peak shape for water, allowing the convenient measurement of water by GC. A sharp water peak shape allows qualitative and quantitative analysis, linear response, great sensitivity, and reproducibility. On this particular chemistry, water has a KRI of 1910 at 100 C isothermal oven temperature.• USP Code: None• Phase: Non-bonded; 1,11-Di(3-hydroxyethylimidazolium)3,6,9-trioxaundecane trifluoromethanesulfonate• Temp. Limits: 30 C to 180 C (isothermal or programmed)
