    Postnova Analytics miniaturized af4 channel cartridge
    Basic setup of an <t>AF4</t> separation cartridge . The shape of the separation channel is defined by the Mylar foil cutout. When all parts are screwed together, the pressure exerted on the edges of the foil pushes them into the membrane and seals the channel. The top plate consists of a solid PMMA sheet with fluidic connections for sample inlet and outlet. The channel bottom contains the frit, supporting the membrane and relaying the fluid pushed through the membrane toward the outlet crossflow. The steel plates on both sides of the assembly are used to compress the chip and withstand pressures in excess of 10 bar.

    Techniques Used: Membrane

    Separation principle in Asymmetrical Field Flow-Field Fractionation (AF4) . Smaller particles with higher diffusion coefficients stabilize (on average) further away from the membrane toward which they are drawn by the permanent crossflow. Thereby, small particles are subjected to faster streamlines than larger ones and accordingly exit the channel more quickly.

    Image of a miniaturized Asymmetrical Field Flow-Field Fractionation (mAF4) cartridge and a commercially available analytical AF4 channel . The smaller size of the mAF4 cartridge makes it more economical and results in shorter analysis times. It is also easier to handle, thereby speeding up general maintenance tasks, such as exchanging the channel membrane.
