One important goal of fire research is to study the
formation and consumption of chemical species in and
around a fire. Instruments which possess rapid temporal
response are required for resolving species
concentration fluctuations and for studying rapid events
such fire suppression. Presently-used probe sampling
methods are slow, and system temporal response is
difficult to determine because it is a complex function
of sampling line length, sample flow rate, and gas
analyzer response time. The limitations of probe
sampling provide motivation to explore new techniques
for rapidly measuring species concentrations in and
