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
