Definitions
- the invention relates to a device for the chromatographic separation of a mixture of substances in liquid form, a module for the chromatographic separation of a substance mixture in liquid form, a chromatography device with at least one such module and a method for producing a device having a plurality of supply and discharge openings for a chromatography device ,
- the invention relates to a chromatographic apparatus for the chromatographic separation of mixtures comprising biological molecules and biotechnologically engineered molecules.
- Biological molecules are typically molecules from natural environments, such as milk or tissue of both animal and plant species.
- Biotechnologically produced molecules are preferably biopharmacentric molecules, for example lipids, proteins, nucleic acids or viruses.
- Chromatography devices have been known for a long time, especially for biopharmaceutical production, but they are usually based on a columnar structure.
- a disadvantage of these columnar chromatography devices was that although the product quality was achieved due to the high precision, a change in the production volume (so-called scale up) was not possible in a simple manner, because this always extensive measurements before commissioning the modified Process volume were necessary.
- a columnar chromatography apparatus is known, for example, from US 7,390,408.
- biopharmaceutical production chromatography devices which are columnar in shape, they are generally filled with particulate chromatography media as described, for example, in US Pat. No. 7,390,408.
- a disadvantage of the columnar Chromatologievoriques is that large column diameters and / or column heights can be realized only with a very high production cost. Furthermore, the high pressures of 3 to 5 bar require very high precision in the production. The height of the column in the chromatography process is essentially limited by the compression of the particles of the particulate matrix and the increasing process pressure. Another disadvantage is that a change in the process volume was expensive.
- porous solid-state matrices are, however, limited to the fact that in the production process for the porous solid-state matrices, which are generally polymerization products, the layer thickness of the porous solid are limited by the inhomogeneity of the pore distribution that occurs in the polymerization process due to heat development.
- a chromatography apparatus which comprises a chromatographic packing which can be embodied in various ways as a stationary phase, for example also as a plate or block mold.
- a stationary phase for example also as a plate or block mold.
- No details are given in US Pat. No. 5,139,680 about the manner of feeding the substance mixture to be separated to the stationary phase. In particular, no information is given as to how the process volume can be changed without extensive measurements before commissioning the modified process volume.
- DE 1, 517,944 shows a separating device and a separation process, in which a filling material serves as one of the phases or as a carrier for one of the phases.
- the filling material according to DE 1, 517,944 are spherical particles which are introduced into a column of a chromatography apparatus.
- the stationary phase is thus a particulate matrix.
- the single ones Spherical particles can be subsequently solidified by sintering after infiltrating the chromatography column.
- the spaces between the individual spherical particles can also be filled with a polymer as filler. Even strips of plastic foams that can be installed between two plates are known from DE 1,517,944.
- a stationary phase which itself as a plate of a polymer, in particular of a polymer, which is obtained by liquid phase polymerization with a very homogeneously distributed porosity, has not become known from DE 1, 517,944. Rather, the device according to DE 1, 517,944 is a device for column chromatography.

- the solid itself is a porous solid matrix which has a very homogeneous pore distribution and is suitable for a chromatographic separation.
- the porous solid may be a substantially homogeneous polymer or consist of layered membranes.
- PMMA is preferred in membranes cellulose membranes. It is particularly preferred if the polymer is obtained by polymerization from monomers in the liquid phase. For example, PMMA is particularly preferred.
- the space requirement of the chromatography device is significantly reduced and the weight is reduced.
- this is made possible by the fact that solid bodies can be layered or combined in modules, and thus the chromatography apparatus provides chromatography volume, above all at height.
- the plate-shaped porous solid allows the use of large chromatography volumes despite limited layer thickness.
- Another advantage is that the plate-shaped porous solid-state chromatography device does not include any moving parts, such as a Chromatography column, which is filled with a particulate matrix and in which the particulate matrix, for example, must be compacted by a stamp.
- the layer thickness of the plates is preferably 0.5 to 15 cm, preferably between 1 cm and 5 cm. Such a layer thickness ensures that the solid produced by polymerization, in particular with liquid polymerization, is homogeneously polymerized and has sufficient homogeneity of the pore distribution for the chromatography.
- the areas of a plate that can be made by polymerization range in size from 1 ⁇ 1 cm to 100 ⁇ 200 cm, in particular from 10 ⁇ 20 cm to 40 ⁇ 80 cm, that is, from areas of 4 cm 2 to 20,000 cm 2 , preferably 200 cm 2 to 3,200 cm 2 .
- Process volume is understood to mean the volume of the liquid which is sent via the chromatography apparatus until the substances bound in the porous pores are released, for example by changing the buffer or the conductivity, and are applied in the eluate.
- the process volume is essentially determined by the required amount of the substance to be chromatographed in the substance mixture and, for example, in a biopharmaceutical production using, for example, mammalian cells, microorganisms corresponds to the fermentation volume of the production fermenter.
- the chromatography volume is determined by the total surface area provided in the porous solid.
- the porous solid of the plate-shaped stationary matrix is preferably made of a polymer material having a homogeneously distributed porosity.
- the polymer material used here is in particular an acrylate, in particular a polymethyl methacrylate (PMMA).
- PMMA polymethyl methacrylate
- the porous, plate-shaped solids are obtained by a liquid polymerization of monomers. Also sintered materials or photonic crystals would be possible if they are connected to a block.
- Homogeneously distributed means that the pores in the polymer material are homogeneously distributed.
- the pores are for the most part, preferably more than 95%, in particular more than 80% connected to each other and thus form a substantially continuous cavity.
- a device In order to charge the plate-shaped stationary phases as evenly as possible with the substance mixtures to be separated in liquid form, a device is provided with a plurality of supply openings, which has a plurality of supply lines for supplying the substance mixture to be separated.
- This device is also referred to as a feeder.
- the device according to the invention is designed so that the feed openings are distributed over the plate surface in such a way that the entire plate surface can be fed via the feed openings with a mixture of substances to be separated.
- a uniform feed is achieved in that the feed opening, for example.
- funnel shape z. B.
- the feed openings are arranged above the surface of the porous solid such that the exit surface associated with each cone in total covers the total area of the porous solid to be charged for all cones.
- the individual feed openings are arranged regularly, in particular in rows and columns.
- the device further comprises a device with a plurality of discharge openings, which serves for discharging the flow and / or the eluate and is referred to as discharge device.
- discharge device By flow is meant in the chromatography and in the present application, the liquid which passes through the porous solid unbound.
- Eluate is understood to be the liquid which is obtained when the substance bound in the porous solid or the bound substances is / are re-applied.
- the plate-shaped solid at a certain pH and / or conductivity, for example a pH 7 or a conductivity of 2 to 10 millisiemens cm '1 .
- Certain substances bind at this pH to the surfaces of the porous solid, for example, to the surfaces provided in the pores.
- the given parameters pH value, conductivity are only exemplary parameters and not limited thereto. The parameters are essentially dependent on the functional groups attached to the pore surface which interact with the mixture to be separated.
- the pH and / or the conductivity is changed, for example by adding a buffer solution, a so-called elution buffer, the substances bound in the solid are desorbed.
- the liquid with the desorbed substances is then also referred to as eluate.
- the eluate thus contains the product.
- the device can also be operated in continuous chromatography.
- the chromatography device is charged with product liquid. Impurities in the product are then bound in the porous matrix. After going through the porous solid is contained in the flow purified product by flow chromatography. The retained in the porous matrix impurities can be solved by adding appropriate solutions, such as buffer, later again from the porous solid.
- the chromatography device according to the invention is also suitable for this purpose.
- a substantially equal length of the feed line is achieved when the feed lines in the plane have a dichotomous branching structure.
- a dichotomous branching structure is characterized by a repeated bifurcated branching.
- Such a dichotomous branching structure also represents a fractal structure.
- Such fractal structures are known, for example, from US Pat. No. 4,537,217, the disclosure of which is incorporated in full in the present application.
- the feed opening is designed such that a uniform distribution of the supplied material over the entire surface of the feed opening on the surface of the solid.
- the supply of the substance mixture from the supply line takes place via an outlet opening substantially horizontally to the surface of the plate-shaped solid in the feed opening.
- the outlet opening which opens substantially horizontally into the feed opening, is located opposite a baffle surface. The horizontally emerging from the outlet opening mixture meets the baffle and is thereby deflected.
- the liquid stream introduced into the feed opening is swirled or rotated in the form of the substance mixture, so that the mixture of substances spreads over the entire surface of the feed opening, ie distributed over the entire exit surface of the example cone-shaped feed opening, into the surface of the plate-shaped body penetrates.
- the individual feed openings are conical or designed as a cone.
- the individual, designed as Koni supply openings are arranged such that the conical cavities overlap. This ensures on the one hand that the entire surface of the plate-shaped body is covered, on the other hand can be achieved by the connection of the individual conical cavities an exchange of the supplied or discharged substance mixture or eluate.
- By connecting the individual feed openings or Koni it comes to a pressure equalization of each interconnected Koni. If all Koni, which serve to feed a surface, for example, the surface of a solid, connected to each other, so can be achieved over the entire area to be charged pressure equalization.
