GC Analysis of Repeat Injections of a QC Test Mix Containing Water on Watercol™ 1460, 110 °C

Conditions

column Watercol 1460, 30 m x 0.25 mm I.D., 0.20 µm (29695-U)
oven 110 C
carrier gas helium, 26 cm/sec
sample 6 analytes in acetone, each at 1 mg/mL except water (at 0.5 mg/mL)
injection 1 µL, 100:1 split
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 does not interfere chromatographically with other small polar analytes. This application shows the ruggedness of Watercol 1460 to repeat injections.
