Characterisation and calibration of active sampling Solid Phase Microextraction applied to sensitive determination of gaseous carbonyls

► The work here presented provides a characterisation of active sampling methodologies for SPME. ► This development is a tool for sensitive determination of gaseous analytes in atmospheric studies. ► It allows fast quantitation of gaseous carbonyls in a wide range of concentrations. ► The implementation makes the SPME methodology transferable to field studies. ► This work allows the automation of SPME determination of atmospheric compounds.
