The optmuzatlon of condltlons for the gas chromatographlc determination of sixteen polycychc aromatic hydrocarbons (PAHs) using the sphtless mJectlon mode 1s described Parameters optlmlzed were the type and amount of solvent, the temperature of the mnjtion port and the column and the purge time A factonal design was used uutlally to ldentlfy the most important parameters Based on this mttlal study, xylene was chosen as the solvent and 100°C was chosen as the best value for temperature of the column The other parameters were optmuzed by using a sunplex method The optlmum condltlons found were 3 ~1 of solvent, 280°C for the mJectlon port and a purge time of 30 s With these condltlons, relatwe standard devlatlons for five rephcate determmattons of 2-ng amounts of PAHs were 3 2-10 8% Keywords Gas chromatography, Optmuzatlon methods, Factonal design, Polycychc aromatic hydrocarbons, Simplex
