An example of the standard GC conditions for screening of the scheduled chemicals is shown as follows.. In the practical analysis, at least two capillary GC columns with diff erent polarity should be used simultaneously. For analysis of decomposition products, highly polar CW-20M or DB-WAX columns are applica-. GC selective detectors to be used for analysis of chemical warfare agents.

At Nippon Medical School, the Department of Legal Medicine and the Advanced Critical Care Medical Center have been cooperating for practical analysis and studies on new analytical methodologies of drugs and poisons in specimens sampled from poisoned patients for more than 20 years since 1980 [1–8]. inside the Ad- vanced Critical Care Medical Center and complicated analysis for identifi cation and quantita- tion is being made at laboratories of the Department of Legal Medicine.

One of the most valuable aspects of the Handbook is the inclusion of specifi c case studies.. Th e 2002 version of the Handbook in Japanese was judged to be highly valuable and led to the production of an English version. Th erefore, these methods provide help and guidance in initi- ating a new analysis, but do not take the place of independently determining limits of detection, quantifi cation and linearity, and the selectivity and precision of the assay in their own hands.

Since various kinds of more powerful and odorless disinfectants have nowadays become available in practical use, the frequency in the use of cresol seems decreasing. Th e toxic eff ects of cresol are due to its corrosive actions, resulting in the destruction of cell membranes and coagulation of proteins, and its suppressive action on the central nervous sys- tem [1].

Th e volatile compounds are purged from a specimen to be trapped by activated charcoal or a column of Tenax j , followed by desorption of the compounds by (pulse) heating and intro- duction into GC (/MS) for analysis. Recently, the headspace SPME method [method (3)] and the combined method [method (4)] have been developed as useful methods for analysis of volatile compounds.. GC/MS analysis of intratracheal gas in an actual case. The data on kerosene and gasoline are shown for comparison.

In this chapter, the methods for analysis of the metabolites are not dealt with.. It is useful for the testing of retention times and as the standards for quantitative analysis.. c) In GC and GC/MS analysis, one or two of carbofuran, carbaryl and ethion (an organophos- phorus compound) are used as IS(s) according to retention time(s) of target compound(s).. Th e solutions of the above ISs should be prepared at the fi nal concentration of 5 or 20 µ g/mL..

Discrimination of commercial products of diarsenic trioxide. In the criminal analysis of poisons, the identifi cation of a poison used for a crime with the one seized is an important task. Although the cost is high, the most useful instrument for such discrimination analysis of inorganic elements is ICP-MS. However, the concentration of a matrix introducible into the ICP-MS should be not higher than 500 ppm..

Al- though the reports on nail analysis are not many, its usefulness seems comparable to that of hair analysis, in view of identifi cation ability of a drug previously administered and estimation of both amount and time (period) of administration [9]. It was in the middle of 1950s when drugs were reported movable from blood to saliva [1]. Recently, saliva is being tried for therapeutic drug monitoring and for detection of the driving under the infl uence of a drug in the world.

Th e advantages of the use of the reversed phase HPLC for analysis of permethrin in serum are the simplicity of pretreatments and rapidness of analysis. For more sensitive analysis, the condensation of permethrin using Sep-Pak C 18 [6] (Waters, Milford, MA, USA) or Extrelut (Merck, Darmstadt, Germany) extraction becomes necessary..

Although there are many reports on toxic and fatal cases due to alkyl nitrites [5], reports on their fatal doses are few. it is estimated that oral ingestion of 10–15 mL of each alkyl nitrite causes serious methe- moglobinemia [6]. Th ere are not many cases of analysis of alkyl nitrites in the fi eld of forensic toxicology. In this chapter, the methods for analysis of the compounds by headspace (HS)-gas chromatography (GC) and liquid-liquid extraction-GC are presented..
