Field flow fractionation magnetic

Type 1 particles Type 2 particles Accumulation wall [Pg.291]

It may be noted that the vertical velocity of fluid (ty) is equal to zero due to unidirectional nature of liquid flow. The two equations are uncoupled first-order differential equations. For a homogeneous fluid, is constant. When the dimension of the magnet is sufficiently large compared to the dimension of the channel, the magnetic gradient is uniform, and thus, C2 is constant. For constants and C2 and the subscript 0 corresponding to the initial values at t = 0, the closed form solution of the above equations is [Pg.291]

The above two equations are coupled as the y coordinate appears in the first Xp equation (equation (7.46)) and the trajectory of the particle is nonlinear. [Pg.292]

This is a cubic equation. It can be verified from the equation that at y = h, we get Xp = 0. By setting y = -h, one can find the distance from the inlet at which the particle meets the bottom wall as [Pg.292]

In magnetic field flow fractionation the separation depends upon how strongly particles are attracted to one pole of a magnet [94]. [Pg.282]

Magnetic field-flow fractionation (FFF) employs static or quasi-static magnetic fields and excludes electromagnetic fields. Electromagnetic fields having frequencies in the kilohertz to megahertz range are used in dielectrophoretic FFF. Static electric fields are used in electrical FFF (see the entry Field-Flow Fractionation Fundamentals). [Pg.968]

Magnetic field-flow fractionation (MFFF) has been the youngest subtechnique of FFF. So far the only work [66] dealing with MFFF defined elementary theoretical principles of the separation, and demonstrated in practice retentions of bovine serum albumin in the presence of nickel(II) ions in a magnetic field of 400 G. A coiled Teflon capillary with an inside diameter of 0.15 cm and length of 304 cm was used as a channel. In the absence of nickel(II) ions no retention was observed. [Pg.514]

Microelectronics technologies are widely used to create new separators able to capture superfine and weakly magnetized particles. The on-chip made separators based on magnetic field-flow fractionation or magnetic chromatography can separate Brownian particles according to their magnetic properties and can be applied for analytical purposes.Apart from... [Pg.150]

A magnetic field flow fractionation unit consisting of a square channel of 1 mm x 1 mm cross section is used to separate magnetic beads of different sizes. The magnetic susceptibility of magnetic bead is equal to 3500. The magnetic beads of 1 pm and 10 pm diameter are submerged in water with susceptibility of -9.035 x 10 . The 1 pm particle is deposited at a mean distance of 500 mm from the enhance of the channel. Calculate the distance at which the 10 pm particle will be deposited. [Pg.302]

MAGNETIC FFF Magnetic field-flow fractionation has been studied in only a few cases dealing with theoretical principles of the separation and retention of bovine serum albmnin in the presence of nickel (II) ions in a magnetic field of 400G and retention of metal oxides. [Pg.1808]
