oven 163 C
carrier gas helium, 26 cm/sec
sample 6 analytes in acetone, each at 1 mg/mL except water (at 0.5 mg/mL)

liner 4 mm I.D., split type, cup design
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 can be integrated and quantified. Sharp peak shapes are also produced for other small polar analytes. This application shows the ruggedness of Watercol 1910 to repeat injections of 60% water.
