A series of experimental condi- (PAHs) and 15 nitrated PAHs (NPAHs) in ambient air par- tions, including extraction solvent, adsorbents, and elution ticulates by applying an in-house built integrated ultrasonic solvent, were systematically studied and optimized. Owing extraction device followed by gas chromatography coupled to its superior ability in purifying particulate matter sam- with mass spectrometry (GC–MS). After integrated ultra- ples, a combination of flower-like-texture Mg–Al layered sonic extraction in the extraction cell, the extract solution double oxide (Mg–Al-LDO) and silica gel was selected as was released through the opened valve into a purification the optimized adsorbent. To our knowledge, few reports on tube containing adsorbents for purification, then concen - this combination of materials exist. The Chromatographia Springer Journals
