“…The particles are assumed to be of negligible size compared with the zone thickness, and therefore the channel. It is however simple to include first-order corrections to account for finite particle size (Giddings 1978;Giddings 1979;Williams & Giddings 1994). It is also assumed that there are negligible particle-wall and particle-particle interactions Williams et al 1997).…”

Quadrupole magnetic field-flow fractionation is a relatively new technique for the separation and characterization of magnetic nanoparticles. Magnetic nanoparticles are often of composite nature having a magnetic component, which may be a very finely divided material, and a polymeric or other material coating that incorporates this magnetic material and stabilizes the particles in suspension. There may be other components such as antibodies on the surface for specific binding to biological cells, or chemotherapeutic drugs for magnetic drug delivery. Magnetic field-flow fractionation (MgFFF) has the potential for determining the distribution of the magnetic material among the particles in a given sample. MgFFF differs from most other forms of field-flow fractionation in that the magnetic field that brings about particle separation induces magnetic dipole moments in the nanoparticles, and these potentially can interact with one another and perturb the separation. This aspect is examined in the present work. Samples of magnetic nanoparticles were analysed under different experimental conditions to determine the sensitivity of the method to variation of conditions. The results are shown to be consistent and insensitive to conditions, although magnetite content appeared to be somewhat higher than expected.

Autofocusing and ESI‐MS analysis of protein digests in a miniaturized multicompartment electrolyzer

Free-solution IEF of protein digests was studied in a newly introduced MicroRotofortrade mark multicompartment electrolyzer. The fractionation was performed in a cylindrical separation chamber divided into ten compartments with or without the addition of carrier ampholytes. In the case of autofocusing mode of operation, the tryptic digest itself served as the mixture of ampholytes leading to the separation of the peptides with well-defined pI's. The focusing process was monitored visually using colored pI markers. The resulting fractions from both modes of the separation were analyzed by CE and electrospray-TOF mass spectrometer using electrospray tips microfabricated in polyimide. Additional experiments, aiming at visualization of the mass flux within the focusing compartments were performed using isotachophoretic migration of color cationic tracers. The study considered the autofocusing of both the peptides with well-defined narrow pI's as well as those showing negligible net charge in a broader pH range. Although not all peptides in the protein digests have well-defined pI's the autofocusing process can preseparate many of them leading to higher S/N in the ESI-MS signals and improved protein sequence coverage.
