Throughout the decades of analytical instrument designs and developments there have been many incidents and scientific improvements, which have assisted to generate major design trend changes. A unique and innovative technology enabled analytical instrument designed to meet the needs of quantitative chemical analysis of polycyclic aromatic hydrocarbons (PAHs) in various environmental compartments. PAHs are a class of very stable organic molecules made up of only carbon and hydrogen and contain two to eight fused aromatic rings. PAHs are formed during incomplete combustion of organic materials such as fossil fuels, coke and wood. These molecules were oriented horizontal to the surface, with each carbon having three neighboring atoms much like graphite. The physicochemical properties and structures of a variety of representative PAHs can be seen in Table 1-2. Epidemiological evidence suggests that human exposures to PAHs, especially Benzo[a]pyrene are high risk factors for carcinogenic and mutagenic effects. There are hundreds of PAH compounds in the environment, but only 16 of them are included in the priority pollutants list of US EPA (EPA, 2003). Many PAHs have also been identified as cancer-inducing chemicals for animals and/or humans (IARC, 1983).
