Specific Activities

A method is described for the preparation of tritiated polycyclic aromatic hydrocarbons with extremely high specific activity in the presence of AlCl3 and HTO. The hydrocarbons are purified by preparative thin layer and paper chromatography. The radiochemical purity of the compounds was proved by paper chromatography and dilution analysis. The following specific activities are reached: Anthracene: 54 Curies/mMol, 7,12-Dimethylbenzanthracene: 19 Curies/mMol, 3,4-Benzopyrene: 24 Curies/mMol, and 3-Methylcholanthrene: 44 Curies/mMol.

The combinatory use of on-chip ultra-thin layer chromatography (UTLC) and surface enhanced Raman spectroscopy (SERS) has been demonstrated to detect mixtures of hazardous food contaminants, polycyclic aromatic hydrocarbons (PAHs), from cooking oil samples.
