Question

Investigators are combing the site of an explosion with mesh screens to collect evidence. The explosion was very large, leaving very little evidence behind. The investigators think that they have collected a part of the original explosive. What tool could they then use to confirm this find?

Answer 1

Answer:

The answer is an ion mobile spectrometer. This tool can detect explosive materials, and a bomb will naturally have explosive materials on it. Investigators will be able to say that a piece of debris with explosive materials was likely part of the original bomb.

Answer 2

Answer: SCANNING ELECTRON MICROSCOPY,

Explanation:Many methods are available for use in an explosion site to determine or confirm the explosive materials or bomb fragment seen or obtained from the site they include the following; SCANNING ELECTRON MICROSCOPY,

CHROMATOGRAPHY-MASS SPECTROMETRY, STEREO MICROSCOPY, CAPILLARY ELECTROPHORESIS.

SCANNING ELECTRON MICROSCOPY, is a technique used to identify or confirm a material by scanning the surface of the material using FOCUSED BEAM OF ELECTRONS IN AN ELECTRON MICROSCOPE.
