Abstract :
In this paper, we present some new column designs for micro-gas chromatography (muGC) columns. Serpentine columns are compared to commonly used spiral columns and are found to give relatively lower height equivalent to theoretical plate (HETP) values. Turns are a major dispersion source for serpentine configuration. We found that sinusoidal compensation structures following the turns give lowest dispersion amongst the several tested turn geometries for serpentine configuration.
