The term NO x represents several forms of nitrogen oxides such as NO (nitric oxide), NO 2 (nitrogen dioxide) and N 2 O (nitrous oxide, also known as laughing gas).In a gasoline engine, NO is the most common form of NO x at around 93%, while NO 2 is around 5% and the rest is N 2 O.
The explosive trace detectors utilizing AFPs, known as Fido Explosives Detectors, were originally developed under the Defense Advanced Research Projects Agency (DARPA) Dog’s Nose program and is now produced by FLIR Systems. The current generation, provides broad-band trace explosive detection and weighs less than 3 lbs.
The use of colorimetric test kits for explosive detection is one of the most simple methods for officers, and widely used method for the detection of explosives. . Colorimetric detection of explosives involves applying a chemical reagent to an unknown material or sample and observing a colo
Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing, formerly known as BackTrack. [2]Parrot Security OS is a cloud-oriented Linux distribution based on Debian and designed to perform security and penetration tests, do forensic analysis, or act in anonymity.
A flame ionization detector (FID) is a scientific instrument that measures analytes in a gas stream. It is frequently used as a detector in gas chromatography . The measurement of ions per unit time makes this a mass sensitive instrument. [ 1 ]
In 1982, AFTE published an official training manual to be used as a modular guide for the training of firearm and tool mark examiners. In 1989, AFTE hosted its 20th Anniversary Annual training seminar in Virginia Beach, VA .
Forensic DNA analysis can be a useful tool in aiding forensic identification because DNA is found in almost all cells of our bodies except mature red blood cells. Deoxyribonucleic acid is located in two different places of the cell, the nucleus; which is inherited from both parents, and the mitochondria; inherited maternally.
The polymer films can be exposed repeatedly to samples due to the reversible nature of the binding of the analytes to the film. The Fido explosives detector can return the fluorescence intensity of the polymer films to near the initial baseline reading by drawing in a new flow of clean air to sweep over the polymer film and desorb the analyte.
