An alternate to the OPC is the aerodynamic particle sizer, which is especially useful where the filtration, deposition, and inhalation properties of the particles are important. The aerodynamic particle sizer a
Separation performance in the conventional cross-flow filtration system Membrane separation performances were examined using a home- made cross-flow filtration setup at the cross-flow velocity of 22 cm s−1 and the temperature was kept at 25 ± 0.5 °C. The effective filtration area of each ...
Elemental analysis The elemental (CHNS) analysis of the HFO and VRO was performed in a Thermo Flash 2000 (Thermo Fisher Scientific, USA) organic elemental analyzer. In a typical analysis, 2.5–3 mg of sample was used. The combustion tube present in the analyzer was heated to around 1000 °...
Reverse osmosis was conducted with a CUBE80-VA cross-flow laboratory filtration unit (SIMA-tec® GmbH, Schwalmtal, Germany) equipped with a membrane cell with an active membrane area of 85 cm2. A flat sheet polyamide RO membrane (TRISEP® ACM2, MANN+HUMMEL Water & Fluid Solutions GmbH,...
The crystals formed under the optimized conditions were harvested through filtration after cooling down the acid solution saturated with (NH4)2SO4 to 4 °C. The scanning electron microscopy (SEM) (Zeiss Supra 35 SEM, ZEISS Microscopy, Jena, Thüringen, Germany) with a Thermo Fisher System 7 ...
