How does an IONSCAN ETD machine work to detect the presence of a target amount of explosive material contained in baggage or on a person or other articles subjected for analysis?
1) The machine works the best when random and continuous selections are made
2) The machine uses electricity to detect the explosives
3) The machine works like an X-ray and takes images
4) The IONSCAN detects microscopic traces of residue (dust particles) and analyzes for the presence of explosives
