3. Surface area Acoustic Wave (SAW) Sensors
Surface area Acoustic Wave sensors are another technological innovation used for explosives trace detection. These sensors do the job by making sound waves that journey together a surface when an electrical sign is used. When explosive particles are present, they change the properties on the seem waves, that may be detected and analyzed.
Noticed sensors are particularly powerful for detecting traces of explosives on surfaces such as luggage, offers, or vehicle interiors. They are sometimes employed at the side of other detection procedures for enhanced accuracy.
four. Colorimetric Detection
Colorimetric detection is a less complicated and more cost-helpful process for pinpointing explosives. This system entails making use of a chemical reagent to the sample, which reacts with explosive residues and will cause a visible colour adjust. When colorimetric detection will not be as sensitive or exact as other strategies like IMS or MS, it is still utilised in certain portable ETDs on account of its low priced and ease of use.
