Forensic chemistry is the application of chemistry and its subfield, forensic toxicology, in a legal setting. A forensic chemist can assist in the identification of unknown materials found at a crime scene. [1] Specialists in this field have a wide array of methods and instruments to help identify unknown substances.
The most volatile chemical condense at the top of the column while the least volatile chemicals to vaporize condense in the lowest portion. [1] The difference in volatility between water and ethanol has long been used to produce concentrated alcoholic beverages (many of these are referred to as "liquors"). In order to increase the concentration ...
Forensic toxicology is a multidisciplinary field that combines the principles of toxicology with expertise in disciplines such as analytical chemistry, pharmacology and clinical chemistry to aid medical or legal investigation of death, poisoning, and drug use. [1]
Volatility (finance), degree of variation over time; Volatiles, the volatile compounds of magma (mostly water vapor) that affect the appearance and strength of volcanoes; Stochastic volatility, in the mathematical theory of probability; Pedersen index, a measure of electoral volatility in political party systems
The DART ion source is a kind of gas-phase ionization, and it requires some sort of volatility of the analyte to support thermally assisted desorption of analyte ions. [14] This limits the size range of the molecules that can be analyzed by DART i.e. m/z 50 to 1200. [1] [15] DART-MS is capable of semi-quantitative and quantitative analysis. To ...
which is a measure of the relative ease or difficulty of separating the two components. Large-scale industrial distillation is rarely undertaken if the relative volatility is less than 1.05 with the volatile component being i and the less volatile component being j. [2]
Relative volatility is a measure comparing the vapor pressures of the components in a liquid mixture of chemicals. This quantity is widely used in designing large industrial distillation processes.
Forensic chemistry – study of detection and identification of illicit drugs, accelerants used in arson cases, explosive and gunshot residue. Computational forensics – quantitative approach involving computer-based modeling, computer simulation, analysis, and recognition in studying and solving problems posed in various forensic disciplines ...
