Applications toxicological analysis

In this present chapter, the applications of multidimensional chromatography to forensic and toxicological analysis are described in detail, being organized by technique. While multidimensional chromatography has not been as widely applied in... 

Today, analytical evaluation is done on a large scale in a computerized way by means of data bases and expert systems (Sect. 8.3.6). In particular, a library search is a useful tool to identify pure compounds, confirm them and characterize constituents in mixtures. Additionally, unknown new substances may be classified by similarity analysis (Zupan [1986], Hippe [1991], Warr [1993], Hobert [1995]). The library search has its main application in such fields where a large number of components has to be related with large sets of data such as environmental and toxicological analysis (Scott [1995], Pellizarri et al. [1985]).

Plasma is the main biological sample used in clinical and toxicological analysis, as concentrations found in this matrix are correlated to the pharmacological effect, as well as to the side and toxic effects. However, oral fluid has also been employed in some specific applications because of the advantages associated to this alternative specimen easy, painless, and noninvasive collection, which does not require qualified personnel, it represents the free analyte fraction, and it has a window of detection similar to that in plasma. Within the possible applications of oral fluid analysis, two are of special relevance ... 

Directions of Analysis Analytical procedures depends on the type of problem set. Unknown circumstances of an event or an unknown toxic factor require the application of systematic toxicological analysis (STA), so that the analytical procedure encompasses as many toxic substances as possible. In cases where the administered toxic compound is known, first of all a course of analysis targeted at this compound is conducted, and a positive result must be confirmed by another independent method. When working on a case in which only the symptoms of the action of an unknown toxic factor are given, the ability to use complementary techniques as well as knowledge of the fields of medicine, pharmacology and pharmacokinetics are of particular importance [53].

In this chapter, we give a taste of the current state-of-the-art of LC-MS in clinical applications. Certainly not all possibilities and applications are discussed in this chapter. Topics discussed are therapeutic drag monitoring (Ch. 12.2) and neonatal screening (Ch. 13.2). In addition, the LC-MS analysis of various classes of drags of abuse, and systematic toxicological analysis are discussed.

The presented method of clinical-and-toxicological analysis is especially important in those situations when at the moment of crime it is impossible to identify the nature of the act of terrorism using known methods of chemical analysis as it was occurred in conditions of tragedies in Japan. The noted coincidence of victims as the result of application of sarin on solid aerosol-carrier possibly proves the elaboration of median lethal inhalation doses, thoroughly prepared composition in conditions of ground application (Matsumoto) and closed space (Tokyo Subway).

Forensic science encompasses a number of different fields of science. In this book, we are explaining the theories associated with high performance liquid chromatography, the different forms that it may take, and its use in some forensic applications. In this chapter, we will examine applications of HPLC in drug analysis, toxicology, analysis of explosives, analysis of coloured materials, and environmental science.

Immunoassays represent very selective and sensitive techniques that have found application in several areas such as clinical chemistry, bioanalysis, pharmaceutical analysis, toxicological analysis, and environmental analysis. The first immunoassays developed were radioimmunoassays, which are very sensitive however, one drawback is the need to work radiochemicals. To circumvent the drawbacks, other labels such as enzymes in combination with photometric measurement have been introduced, however, at the expense of sensitivity. With the development of fluoro-immunoassays (FIAs) an improvement in sensitivity was obtained and by introducing chemiluminescence in immunoassays, a sensitivity equivalent to radioimmunoassays was achieved. In this article, different variations and techniques of luminescence immunoassays are described.
