The Frog 4000 is a hand-held micro-system for detection of
benzene, toluene, ethylbenzene, and xylenes (BTEX) and
other volatile organic compounds (VOCs ) in air, water,
Miniaturization of analytical chemistry equipment is the basis of FROG 4000s
design. The system incorporates a micro preconcentrator which
is coated with designer nanoporous materials. The coatings have
affinity for specific aromatics like BTEX or chlorinated VOCs.
The micro preconcentrator has an integrated heater that desorbs
the sample to the GC column.
Defiant's micro GC separates the
major components of BTEX in under 5 minutes.
The GC column
also has an integrated heater that enables controlled temperature
ramp chromatography for better separations and to achieve
temperatures needed for late eluting compounds.
