2. Floor Acoustic Wave (Observed) Sensors
SAW sensors run by utilizing significant-frequency sound waves to detect explosives. These waves are produced on the surface area of the sensor materials, and when an explosive residue is current, it alters the sample from the wave. The sensor picks up these variations and alerts the consumer into the prospective existence of explosive substances. Observed-primarily based detectors in many cases are used for transportable or handheld products as They may be commonly more inexpensive and convenient to use than IMS-centered methods.
3. Colorimetric Detection
Colorimetric explosive trace detectors make use of a chemical reagent that variations color when it reacts with explosive residues. The surface area or sample in problem is swabbed, and if explosive traces are present, the reagent will alter colour, signaling the detection. Although this technological know-how is much less innovative than IMS or Observed, it provides a price-effective substitute for standard protection checks. Colorimetric detectors will often be used as secondary screening resources or for non-vital programs.
four. Mass Spectrometry (MS)
Mass spectrometry is considered the most Highly developed and specific technology for detecting explosives, although it is typically found in laboratory or stationary methods. This technique operates by breaking down a sample into billed particles and measuring their mass-to-cost ratios. The ensuing information allows establish particular explosives with Intense accuracy. Although mass spectrometry-dependent ETDs are certainly not usually Employed in moveable devices, they provide higher-level detection capabilities in settings that need most sensitivity and precision.
