Analysis of organic/inorganic analytes in environmental samples by packed capillary chromatography
- Univ. of Leeds (United Kingdom); and others
Recent progress in the development of techniques for packing of high efficiency capillary columns has enabled the concept of unified chromatography to be realised. Packed capillary columns offer the advantages of both packed column (high loading capacity, wide range of stationary phases) and capillary column (speed of analysis, high resolution) techniques to produce a versatile and efficient analytical procedure. For the detailed investigation of fossil fuel and environmental samples the rapid growth of packed capillary chromatography offers the unique opportunity to analyse both organic and inorganic components as the column can be operated in both gas chromatography (GC) and supercritical fluid chromatography (SFC) modes. In this study, the use of packing capillary columns, prepared in-house is investigated for both high pressure GC and SFC using helium and CO{sub 2} as the mobile phase respectively. Several spiked and real world samples have been used to demonstrate the potential of packed capillary columns in the analysis of organic and inorganic analytes in fuel and environmental samples.
