This test mixture was chromatographed under varied conditions of the plasma support helium flow rate and microwave input power. A relatively high value of (3.9±0.3)×10was found for the fluorine to carbon selectivity, with detection limits for fluorine as low as 1.3±0.2 pg(F)⋅s−1. These levels for the selectivity and for the detection limit compare favorably with previous reports found in the literature for other GC-MIP systems. ©1999 John Wiley & Sons, Inc.
