Dual-zone reactor capable of generating metal oxide nanoparticles (Zone 1) in the presence of a high sooting 1-MN fuel (Zone 2) coupled with a cold finger for condensation of paramagnetic species. Soot was collected through a moveable probe stationed at sampling ports denoted I–IV in the isothermal region as well as sampling points A (700 °C) and B (475 °C) in the quenching zone of reactor, and sampling point C (80 °C) in the exhaust stream.
