2. Surface area Acoustic Wave (Observed) Sensors
SAW sensors function by making use of higher-frequency audio waves to detect explosives. These waves are created to the surface of the sensor material, and when an explosive residue is current, it alters the sample with the wave. The sensor picks up these adjustments and alerts the person towards the probable existence of explosive substances. SAW-centered detectors will often be utilized for moveable or handheld devices as They can be frequently much more reasonably priced and simple to operate than IMS-based mostly devices.
three. Colorimetric Detection
Colorimetric explosive trace detectors utilize a chemical reagent that variations coloration 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 shade, signaling the detection. Although this technology is considerably less sophisticated than IMS or SAW, it offers a price-successful alternate for simple protection checks. Colorimetric detectors will often be applied as secondary screening instruments or for non-critical applications.
4. Mass Spectrometry (MS)
Mass spectrometry is considered the most Innovative and exact technological know-how for detecting explosives, although it is typically present in laboratory or stationary programs. This method will work by breaking down a sample into billed particles and measuring their mass-to-cost ratios. The ensuing data can help detect particular explosives with Intense precision. Though mass spectrometry-primarily based ETDs will not be frequently Employed in moveable units, they offer superior-degree detection abilities in options that have to have most sensitivity and precision.
