Chapter 12 Flashcards
A sensor that responds to a target analyte or analytes based on a biochemical mechanism
Biosensor
The shattering power of an explosive or explosive device
Brisance
The use of chemical reagents and developers to assist in the visualization of evidence; also refers to indirect imaging of samples by conversion of signals such as IR or MS data to viewable data
Chemical imaging
Burning or combustion that propagates at less than the speed of sound
Deflagration
Explosive combustion driven by pressure and a compressive shockwave
Detonation
A compressive pressure wave (shockwave) that propagates through an explosive and causes combustion
Detonation wave/detonation shock wave
A very sensitive spectroscopy for analyzing the absolute configuration (AC) and conformation of chiral compounds
ECD
Combustion that propagates faster than the speed of sound
Explosion
The power of explosives scaled to that of picric acid and expressed as a percentage
Explosive power index/explosive index
The series of explosive materials used to detonate a high explosive
Explosive train
An explosive that is relatively stable and insensitive to heat and shock
High explosive
Explosives that are created by combining easily obtainable ingredients such as sugar and fertilizer
Homemade explosives
Devices that are placed or fabricated in an improvised manner incorporating destructive, lethal, noxious, pyrotechnic, or incendiary chemicals and designed to destroy, incapacitate, harass, or distract
IED
An explosive or explosive device made from existing or homemade components
Improvised explosive
An explosive that detonates easily and is sensitive to heat or shock
Low explosive
An assay such as an immunoassay that detects more than one compound or class at a time
Multiplex assay
A sensitive high explosive used to initiate detonation of a relatively insensitive high explosive
Primary explosive
Brisance
Pushing power
A type of mass spectrometry where the mass-to-charge ratio of the sample ions is measured while the ions are held in a stable orbit by an electric field generated by four parallel electrodes
Q-ToF
The power of an explosive as compared to some standard such as picric acid or TNT
Relative explosive power (REP)
An relatively insensitive explosive that is detonated by a primary high explosive
Secondary explosive
Compounds added to propellants and explosives to increase sensitivity to detonation
Sensitizers
An area of very high pressure moving through the air, earth, or water
Shock wave
A variant of Raman spectroscopy that allows highly accurate chemical analysis of objects beneath obscuring surfaces
Spatially offset Raman spectroscopy (SORS)
One of several sets of rules used to approximate the mixture of products produced in an explosion
Springall Roberts rules
Detection at a distance that doesn’t require physical contact between the sample and the detector
Stand-off detection
An extremely insensitive explosive
Tertiary explosive
