Here, 2,200 mL of whey were processed with HGMF to purify 111 mg lactoferrin with polyglutaraldehyde coated silanized magnetic beads. A further processing step was the separation of lactoferrin from crude whey in a five cycle process with 2 L of whey feedstock batches (Brown et al., 2013).

Definition. Magnetic data are measurements of the magnetic field (generally of its intensity). Corrections of magnetic data are processing operations designed to remove unwanted features in the data. Enhancements of magnetic field data are processing operations designed to preferentially accentuate the expression of a …
