| Abstract: | In this issue, PAHs on the atmospheric particles are extracted by super-sonic and analyzed by GC/MS. The extracted PAHs samples need no purification, and can be analyzed directly. The extraction time is shorter while the extraction efficiency is higher. Using the SIM mode of the MS system, the qualification and quantification PAHs can be done. The recovery is among 84.5% to 108.5%, and the differentiation coefficient is 3.1% to 14.5%. |
