Abstract
The utility model relates to a self-column loading device for loading constant phases to a chromatographic column, which is composed of a column joint, a fixing nut, a column body, a fixing nut and a column connector which are orderly connected. Except for the column connector, the other components of the self column loading device are universal with the chromatographic column, and a high-efficiency liquid chromatograph can be conveniently connected with the self column loading device. The self column loading device has the advantages of simple structure, convenient connection, low cost, good sealing performance and no leakage, can load columns under high pressure and is suitable for loading analyzing type and preparing type chromatographic columns in laboratories.
Description
Technical field
The utility model belongs to the chromatographic resolution Instrument technology field, is specifically related to a kind of being used for toward the self-chambering column device of chromatographic column filling stationary phase.
Background technology
The core of high performance liquid chromatography is a chromatographic column, and chromatographic column depends mainly on fixed phase stuffing efficiently, but the filling quality of chromatographic column also has very big influence.The method of chromatography column has two kinds of dry method and wet methods, and general bulky grain (as external diameter greater than 20 μ m) can be used dry-packing.High efficiency packing in recent years has been to use inorganic oxide and organic porous copolymerization microsphere of granule (as 10,7,5,3 μ m) to make matrix, and the filler of these small particle diameter is generally filled with wet method.Wet method is filled the homogenate method that is also referred to as.The now commercially available analytic type and the filling multipurpose high-pressure homogenate method of preparation type prepacked column, this fill method will use the high-pressure homogenization packing column machine, and to the equipment requirements height, and it is big once to adorn the post scale, is not suitable for a small amount of several root chromatogram columns of laboratory self-chambering.Though the product P oros of U.S. AppliedBiosysterms company self-chambering column device is fit to the laboratory from the luggage post, and is on the high side, and when dress stainless steel chromatogram post, also need to acquire an accessory that connects cylinder and column filler.
Summary of the invention
The purpose of this utility model provides a kind of chromatographic column wet method that is used for and fills, can be high pressure resistant, and low price is suitable for the self-chambering column device that use in the laboratory.
For achieving the above object, the technical scheme that adopts is: a kind of self-chambering column device, comprise cylinder, place the hold-down nut at cylinder two ends respectively, its characteristics are: column joint and described cylinder and the hold-down nut that places the cylinder two ends, and column connector connects successively, and column joint center pit upper end internal thread can connect with the joint screw thread of highly effective liquid phase chromatographic system.
The column connector other end can be with treating that the hold-down nut of packing one end is threaded.The center pit internal diameter of column connector is less than the internal diameter for the treatment of packing, and material is a stainless steel.
Advantage of the present utility model is: can be connected with high performance liquid chromatograph easily, use the stubborn joint of hand of polyetheretherketone (PEEK) material just can couple together high performance liquid chromatograph and self-chambering column device easily, and under high pressure can the leakage good seal performance.The column connector two ends are threaded, and are easy to install, and cost simple in structure is low, and the self-chambering column device is except that column connector, and all the other parts and chromatographic column are general, as use old chromatographic column further to reduce cost.
Description of drawings
The structural representation of Fig. 1 self-chambering column device.
The cross-sectional view that Fig. 2 column connector is connected with cylinder.
1-column joint among the figure; The 2-hold-down nut; The 3-cylinder; The 4-hold-down nut; The 5-column connector; 6-treats the hold-down nut of packing; 7-treats packing; The 8-cutting ferrule.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 as seen, the utility model self-chambering column device comprises cylinder 3, places the hold-down nut 2 and 4 at cylinder 3 two ends, the column joint 1 that hold-down nut 2 other ends connect, the other end joint pin connector 5 of hold-down nut 4 respectively.
Fig. 2 is the structural representation that column connector 5 and cylinder 3 are connected section, the end of cylinder 3 all is provided with coniform cutting ferrule 8 usually, the intimate of the endoporus of cutting ferrule 8 and cylinder 3 is fitted, column connector 5 joins with cylinder 3 and cutting ferrule 8, and be connected with the external thread of column connector end by the internal thread of nut 4, fastening fixing.When installing and using, the other end of column connector 5 is connected with an end for the treatment of packing 7 with the same manner, and is fastening fixing by placing the hold-down nut 6 for the treatment of packing 7 one ends to be threaded.
When the utility model is used to adorn post, at first according to treating that the specification of packing takes by weighing certain filler and is made into homogenate, be ready to high performance liquid chromatograph, maximum pressure value is set, then will treat that as Fig. 1 packing and self-chambering column device connect, backing out column joint 1 pours the homogenate for preparing into again from the upper end of self-chambering post, up to filling the column joint 1 of screwing on again, vertical fixing on the top of the shelf, use the PEEK hand to twist joint self-chambering column device and high performance liquid chromatograph are coupled together, use the pump of high performance liquid chromatograph to adorn post.The self-chambering column device can be connected with high performance liquid chromatograph easily by general column joint 1, and under high pressure can leakage.The center pit aperture of column connector 5 makes the column cap of dress post end back chromatographic column smooth less than treating the packing internal diameter, and no depressed phenomenon removes the self-chambering column device, with blade the filler entrance point is wipeed off again, promptly can be used for chromatographic resolution.
Self-chambering column device column connector 5 materials that the utility model provides are stainless steel, can under high pressure adorn post, and good airproof performance is non-leakage, and the dress post is convenient, and low price is applicable to laboratory oneself filling analytic type and preparative scale chromatography post.
