Preferred Label : furnace pyrolysis;
Detailed label : furnace pyrolysis in spectrochemical analysis;
IUPAC definition : A flowing stream of gas (hydrogen, oxygen, nitrogen, chlorine, etc.) required to produce
volatile species of the elements being determined, is passed over the test sample
in a heated furnace. The analytes leave the furnace in the gas stream, or are entrained
by a carrier gas. The analytes in the gas stream may be collected in an absorbing
solution, on a carbon or other filter or by condensation on a cool surface. In the
case of mercury this can also be done by amalgamation with a noble metal. The analytes
may then be swept and released from the trap, by heating, into a sampling source for
analysis.;
