For GC analysis, the substance to be analyzed must be in the gaseous form. Because of this, the analysis of many organic compounds requires that injections, columns, and detectors are kept at relatively high temperatures. However, many organic compounds are thermally unstable. In such cases, it is necessary to convert the substance to be analyzed to a more volatile derivative appropriate for GC analysis. GC derivatizing reagents such as silylating, acylating, and alkylating reagents are used for this conversion.
Meanwhile, GC has been used for the analysis of biogenic substances. This generally requires the use of various derivatizing reagents. As an example, trimethylsulfonium hydroxide 1 can easily convert fatty acids, fatty acid esters, and glycerides into their methyl esters in a single step through the pyrolysis of the corresponding sulfonium salts 2.1) The low-boiling by-product, dimethyl sulfide, does not disturb the chromatographic separation of the samples. Therefore, the method using 1 is suitable for detection not only of longer chain fatty acids but also of relatively short chain fatty acids. 1 has been successfully applied for sample preparation in the analysis of fatty acids in microorganisms and human blood serum.2)

Genetic information is stored in DNA as combinatorial codes held in nucleosides and nucleotides, in which form it is passed from parents to their offspring. Analogs of nucleosides and nucleotides are used clinically as medicinal agents such as reverse transcriptase inhibitors. Therefore, the preparation and development of these species as effective, selective and nontoxic antiviral and antitumor agents has been the subject of intense research.1)
In addition to this, the development of Polymerase Chain Reaction (PCR) methodology has brought a dramatic change and rapid development in studies of DNA. At the current time the draft version in decoding and mapping human genome has been almost completed, and the functional analyses of genome and analyses of "Single Nucleotide Polymorphism" (SNP) are being vigorously pursued. Discovery of the RNAi process has facilitated the fast progression of studies of RNA. At the same time, chemically synthesized oligoDNA and oligoRNA have been studied as potential antisense DNAs, siRNAs and DNA aptamers; as oligonucleotide therapeutic agents, primers for PCR method, and elements of DNA computers.
