During volatile analysis, samples are purged with an inert gas in order for the
Volatile Organic Compounds (VOCs) to be swept out of the sample matrix and
onto an analytical trap. For years, the established and recommended purge flow
rate and time has been 40ml/min for 11 minutes. However advances in
instrumentation technology have led to the potential for greater efficiencies in
conducting VOC analysis. This study reviews four sets of time and flow
parameters and their respective outcomes.
