    Abstract: The present invention comprises a novel multimodal chromatography sequence of short length alternating adsorption and size exclusion media operating with gradient elution. The novel multimodal chromatography in an oscillating series utilizes the alternating solvent exchange media to reposition the active region of separation back in phase with the target solutes.Each solvent exchange column bed length in the sequence is designed to achieve a subtle decrease or increase in the solvent gradient (or salt gradient) concentration associated with the two solutes of interest which results in an extension of the active separation or increasing differences in solute velocity for two solutes of interest.The novel oscillatory chronographic system demonstrates much improved separation capability as shown by a one dimensional model.

    Abstract: A clamping device for clamping a plurality of columns for sample preparation provides a plurality of clamping blocks and a displacement mechanism for displacing at least one clamping block relative to an opposing clamping block between an open position and a clamping position. At least three clamping blocks are retained in a row one behind the other on a guiding rail so that at least two columns can be clamped in an axial direction one behind the other between the clamping blocks. First and second slidingly displaceable clamping blocks of the least three clamping blocks are retained on the guiding rail and connected to the displacement mechanism by coupling means so that an actuation of the displacement mechanism from the clamping position into the open position brings about a displacement of all the slidingly displaceable clamping blocks and the columns are released.

    Abstract: Provided herein are methods of performing chromatography with gamma-irradiated chromatography resin that include providing a chromatography column including a gamma-irradiated chromatography resin; performing a first cycle of chromatography through the column, where the cycle includes exposing the chromatography resin to a denaturing buffer; and performing at least one additional cycle of chromatography through the column. Also provided are integrated, closed or substantially closed, and continuous processes for manufacturing of a recombinant protein that include the use of at least one chromatography column including gamma-irradiated chromatography resin, where the gamma-irradiated chromatography resin is exposed to denaturing buffer during each cycle in the process, and reduced bioburden buffer is used in the process.

    Abstract: Method and apparatus for characterizing drug-modified polymers, macromolecules, proteins, antigens, antibodies or nanoparticles and quantitative determination of their impurity profile by two-dimensional liquid chromatography analysis. The first dimension is preferably size exclusion chromatography (SEC)—which is also known as gel permeation chromatography in case of non-aqueous samples (GPC)—for complete molecular weight analysis of nanoscale particles. It is not just included the application of separating small molecules from big molecules, but it is also the separation of different sorts of oligomers (e.g. monomers, dimers, trimers, tetramers). The second dimension is adapted for separating and characterizing small molecules which can be impurities or non-reacted modifiers with high-performance liquid chromatography (HPLC). Between the dimensions it is feasible to use solid phase extraction column(s) to collect small molecules, wash off or change solvent, or minimize broadening of their peaks.
