two. Surface Acoustic Wave (Noticed) Sensors
Observed sensors function through the use of higher-frequency sound waves to detect explosives. These waves are created on the surface area of the sensor material, and when an explosive residue is present, it alters the sample from the wave. The sensor picks up these variations and alerts the user towards the opportunity existence of explosive substances. Observed-primarily based detectors are often employed for portable or handheld devices as They can be typically a lot more very affordable and user friendly than IMS-primarily based programs.
3. Colorimetric Detection
Colorimetric explosive trace detectors utilize a chemical reagent that adjustments shade when it reacts with explosive residues. The area or sample in question is swabbed, and when explosive traces are existing, the reagent will change colour, signaling the detection. Although this technological know-how is much less refined than IMS or Noticed, it provides a price-efficient alternative for standard protection checks. Colorimetric detectors will often be applied as secondary screening equipment or for non-essential apps.
four. Mass Spectrometry (MS)
Mass spectrometry is easily the most advanced and precise technological know-how for detecting explosives, although it is often located in laboratory or stationary methods. This method will work by breaking down a sample into billed particles and measuring their mass-to-cost ratios. The ensuing info aids discover unique explosives with extreme accuracy. While mass spectrometry-based ETDs usually are not frequently Utilized in transportable products, they supply significant-stage detection abilities in configurations that have to have most sensitivity and precision.
