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.
