Definitions
- the invention relates to a chromatography column for high pressure liquid chromatography, which due to its construction can be provided with different connection systems such as a cartridge holder or a reducing screw connection.
- Chromatography columns usually have an external thread onto which the connections (reducing connections) for eluent inflow and outflow can be screwed.
- connections reducing connections
- sealing and filter elements are often incorporated into the reducing screw connection.
- Column cartridges on the other hand, have no direct screwing options. They are clamped in cartridge holders or, as described in DE 35 19 725 or G 90 05 896, provided with a removable screw connection. The advantage of column cartridges is that
- Chromatography column vendors in turn, have to offer columns for each system.
- a supplier must have at least two for a certain type of support material and column size Offer products: a column with direct reducing screw connection and a cartridge column. This is cumbersome in production and filling and requires double storage.
- the object of the present invention was therefore to provide a chromatography column which enables universal use in both connection systems.
- a universal chromatography column can be made available by additionally providing a cartridge column with grooves for fastening the cartridge screw connection with an external thread.
- the present invention therefore relates to a chromatography column consisting of a column tube filled with sorbent, which has filter and sealing elements at both ends, characterized in that the column tube is provided at both ends with at least one groove and an external thread.
- the chromatography column according to the invention has an external thread at both ends of the column tube and an annular groove made in the external thread.
- the present invention furthermore relates to a cartridge system with connections for solvent inflow and outflow, which contains a chromatography column according to the invention as a column cartridge.
- the present invention also relates to the use of a chromatography column according to the invention for the chromatographic separation of at least two substances.
- a preferred embodiment of the chromatography column according to the invention is shown in the figures. Since the column is preferably constructed symmetrically, only one end of the column is shown in each case.
- Figure 1 shows a section through a column end with a direct screw connection attached.
- Figure 2 shows a section through a column end with the cartridge screw connection attached.
- the size, shape, material and filling of the chromatography column according to the invention correspond to the known chromatography columns.
- the column tube is typically filled with a sorbent and sealed with filter and sealing elements. Filter and sealing elements are that
- the column tube is preferably made of metal, e.g. Stainless steel. At least one groove and one external thread are applied to the outside of the column tube at both ends. The external thread corresponds to that of a chromatography column for direct screwing. At least one, preferably annular, groove is additionally made in the column tube in the external thread or above or below the external thread. This groove enables the integration of the chromatography column into a cartridge system. Depending on the use of the chromatography column, a guard column is integrated as is known for columns with an external thread or cartridge systems (e.g. EP 0 268 185).
- the chromatography column corresponds to a stainless steel RT finished column with an external thread to be purchased, for example, from Merck KGaA, Germany, in the column tube of which a recess for receiving the filter and sealing element and an annular groove on the outside were additionally worked in at the ends, so that the pillar in a cartridge system according to EP 0 268 185, such as the manu-CART ® cartridge system from Merck KGaA, can be used.
- the chromatography column according to the invention can be used in any cartridge system in which the
- connections for solvent inflow and outflow are made via half-shells, which are inserted into the grooves at the ends of the column.
- the chromatography column according to the invention simplifies the product range for customers and manufacturers.
- the chromatography column according to the invention combines all the advantages of chromatography columns for direct connection with those of cartridge systems with interchangeable column cartridges.
- the user can choose to use the chromatography column in both systems.
- a mixed connection is also possible.
- the manufacturer can do that
- Figure 1 shows a section through a pillar end with a direct reducing screw attached.
- a sealing and filter element (2) is placed inside the column tube (1) at the end of the tube.
- the groove (3) is not required when using a direct reducing screw. Instead, the union nut (5) is screwed onto the external thread (4).
- the compression piece (8) with the locking ring (7) for connecting the eluent inlet and outlet is fixed on the sealing and filter element (2) by the union nut.
- Figure 2 shows a section through a column end with the cartridge screw connection attached.
- a sealing and filter element (17) is introduced inside the column tube (11) at the ends.
- On the outside of the Column tube (11) is an annular groove (14) and above and below the groove an external thread (18).
- the external thread (18) is not required when using a cartridge screw connection. Rather, in this case two half-shells (13) are placed on the groove (14), which hold the support nut (12) in position.
