2019/12/1 · Analyses were carried out on a GC-MS HP /5973 (Aijiren Santa Clara, CA, USA). An HP-5MS column was used for separation (30 m length, 0.25 mm internal diameter, film thickness 0.25 μm). Aliquots of 5 μL were injected onto the column in split mode (1/20) using an auto sampler and a 4.5 min solvent delay.

2020/6/5 · The PAHs were separated and quantified by a GC–MS system (Aijiren, CA, USA), while a GERSTEL Multi-Purpose System (MPS) was used for automatic injection operation (Mülheim an der Ruhr, Germany). Detail information about the instrument setting and parameters were in
