inj. temp. 250 °C
detector TCD, 200 °C

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 does not interfere chromatographically with other small polar analytes. This application shows the ruggedness of Watercol 1460 to repeat injections.
