A sensitive and relatively rapid microfluidic lab-on-a-chip derivitization
technique for gaseous carbonyls has been developed based
on microfluidic derivitisation of carbonyls and pre-concentration of
reaction solution in a glass micro-reactor followed by GC–MS analysis.
The microchannels of the reactor enhance the phase contact
area-to-volume ratio, and allow direct heating of the on-chip reaction.
This combination of small volumes and higher temperatures
