Samenvatting
Miniaturization of GC column is of primary importance in space exploration and field analysis. In this study, GC columns with radially-elongated pillars (REP) (L= 70 cm, 75 μm deep and 6.195 mm wide) were coated, then tested in comprehensive two-dimensional gas chromatography. Stationary phases (apolar PDMS, medium polar RTIL based on monocationic phosphonium derivative and polar PEG-1000) were successfully coated using the static method. The solvent evaporation step was optimized using programed vacuum pressure improving the efficiency by approximately 15%. The best efficiency reached up to N = 62,000 theoretical plates. A separation of a mixture of 11 volatile
compounds using a temperature program on a PDMS-coated chip was achieved in les than 36 s with conventional GC system. The coated chips were tested using a microfluidic reverse fill/flush flow modulator in a GC×μGC system. The REP columns showed a high compatibility with the operating conditions in terms of flow rate. A particularly promising feature of the REP columns is their capability to combine high efficiency with high flow rate which is important to obtain an efficient re-injection using microfluidic modulators.
