“…However, the Langmuir isotherms are recognized to be thermodynamically inconsistent for multicomponent ion‐exchange systems (2). Moreover, the effect of ionic strength (salt concentration) on protein adsorption is not explicitly expressed in these models (2, 3).…”

“…However, most researchers claim that for a given column size, much lower (up to 1 order of magnitude) flow rates should be used if the column is to be operated in the displacement rather than the elution mode. Otherwise a significant loss in product purity and recovery is unavoidable (1, 4, 9). The typical improvement of displacement separations at low flow rate is attributed not only to an increase of the plate number but also to the time available for development of the isotachic train in the column.…”

“…Displacement chromatography is a predominantly preparative mode of chromatography, which is assumed to offer certain advantages in high‐resolution separations of complex multicomponent mixtures of costly biologicals such as recombinant proteins (1, 2). Since the displacement process takes advantage of the nonlinearity of the adsorption isotherm, a chromatographic column operated in the displacement mode can process higher feed loads than a similar column operated in the elution mode.…”

“…(LEAL et al 2002) Na década de 1980, houve grande desenvolvimento nos processos de separação aplicados a processos bioquímicos, tanto para aplicações analíticas como para produção industrial de proteínas e enzimas (PASECHNIK,1995). No entanto, para viabilizar a produção de compostos biológicos é preciso ainda desenvolver processos de menor custo com alta eficiência de produção e recuperação, bem como de fácil operação (FREITAG, 1998).…”
