Question

Fire science evaluation of suspected accelerant chemical residues left after a fire by gas chromatography can identify (Multiple answers)

1 weathering in a sample

2 volatile components of a sample

3 the fingerprint of the sample

4 all of the chemical components of the accelerant

5 an exact match to a volatile accelerant

1,2,4 is not correct

1,2,5 is not correct

1,2,3,5 is not correct

Answer 1

Correct answer: 4 all of the chemical components of the accelerant OR 1,2,3,5 is not correct

Volatile compounds will not be there to examine, since it's name is volatile, hence they will goes out to atmosphere (by either sublimation or evaporation methods).

Gas chromatography is used almost exclusively for separation and measurement of components of the suspected accelerant.
