摘要从安大略西部的汉密尔顿港的底质、悬浮物、煤焦油污染的沉积物和淡水贻贝中分离出高分子量多环芳烃（PAH）组分。异构体分子质量PAH馏分使用正相HPLC法制备。通过大气压化学电离（APCI）LC-MS分析了高分子量PAH馏分，并比较了所得的色谱图。还简要描述了不同HPLC移动的相对质谱仪仪器性能的影响。
Abstract High molecular mass polycyclic aromatic hydrocarbon (PAH) fractions were isolated from organic solvent extracts of a variety of matrices including bottom sediments, suspended sediments, coal tar-contaminated sediments and freshwater mussels from Hamilton Harbour (western Lake Ontario). Isomeric molecular mass PAH fractions were prepared using a normal phase HPLC method. The high molecular mass PAH fractions were analyzed by atmospheric pressure chemical ionization (APCI) LC-MS, and the resulting chromatographic profiles were compared. The effects of different HPLC mobile phases on mass spectrometer instrument performance are also briefly described.
