A miniaturised preconcentrator device (μPCD) filled with CarbosieveS-II was coupled with a miniaturised
gas chromatograph (μGC) and was tested with focus onethylene gas measurement.
The application of the μPCD results in an increase of the system sensitivity by a factor of 23 from 140 ppmv
to 6 ppmv using an ethylene detector based on a metal oxide sensor.
