英文摘要: The integration of two dimensional chromatography system (LC-GC) has ability for clean-up, enrichment,pre-separation and high resolution separation for the sample. The coupling of LC-GC with FTIR can notably improve the detection ability of conventional (light pipe)GC/FTIR system. The interface of LC-GC system employs retention gap technique(15 m x 0.53 mm i.d. retention gap column and 4 m X 0.25 mm i.d. precolumn) with on-column injection and partially concurrent solvent evaporation with early vapor exit. The applicability of the method is demonstrated by the analysis of odoriferous pollutants (phenolic compounds)in the cooling water with 15 cm x 2 mm i.d. silica LC column and 35 m x 0.25 mm i.d. OV-101GC column under the conditions of haxane/dichloromethane (80 : 20) as the mobile phase(0.3 mL/min) of LC,N-2 as the carrier gas in GC and solvent evaporation temperature 80 degrees C,inlet pressure of 0.2 MPa etc. The method of on-line coupled LC-GC/FTIR is a reliable analytical tool for microcomponents in complex mixtures.
