AbolishedAir quality--Determination of benz［a］pyrene in ambient air--High performance liquid chromatography
环境空气 苯并［a］芘测定 高效液相色谱法
Application Summary AI generated
This standard specifies the use of high performance liquid chromatography (HPLC) to determine the concentration of benz[a]pyrene in ambient air samples. It is applied in environmental monitoring and air quality assessment contexts, particularly for measuring polycyclic aromatic hydrocarbons (PAHs) in urban or industrial atmospheres. The method is used by environmental laboratories and regulatory agencies to evaluate pollution levels and ensure compliance with air quality standards.
