Watercol 1910, Non-bonded; 1,11-di(3-hydroxyethylimidazolium)3,6,9-trioxaundecane trifluoromethanesulfonate phase
column type
capillary extremely polar
General description
- 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)
