Abstract

PURPOSE:To automate loading of developed samples on plural bar-like developing elements by mounting said elements radially around a shaft and turning the shaft or a load injector around the axial center. CONSTITUTION:A revolving shaft 2 is so turned and set that an injector 3 is located right above one of developing elements 6 mounted to the shaft 2. An arm 8 is moved horizontally to locate the preceding end of an injector 3 right above the loading position of a developing sample where the arm is fixed. In succession, the angle of one revolution of a pulse motor 4 is set at 45 deg. by setting a setting knob 10. After the sample is loaded upon one element 6 from the injector 3, an operating button 11 is pushed to turn the shaft 2, that is, the element 6 by 45 deg. and to load the sample again on the another element 6. The sample is loaded successively on the 8 elements 6 by repeating said operations.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for use in chromatography, and more particularly to an apparatus for loading a developed sample onto a rod-shaped developing element. The purpose is to propose a device that can automate the loading of developed samples onto multiple rod-shaped development elements.

Conventionally, in order to load a developed sample onto a rod-shaped development element, for example, a plurality of elements are arranged in parallel at a predetermined interval using a rond, and a spotting ruler is placed on top of the rod, and a quantitative loading injector is placed at a predetermined position on the element. It was loaded by dropping the sample from the container. This operation required manual operation to change the position of the developing element and load the sample, which required a lot of manpower and was a heavy burden.

This invention has been made in view of the above circumstances, and its gist is that it is a single product in which a plurality of rod-shaped deployable elements are oriented and joined in the radial direction around one point, or a horizontal plane in which multiple rod-shaped deployable elements are formed separately. It has a vertical shaft that can be attached in an radially inward direction and a developed sample loading injector, the shaft or injector is rotatable about the axial center, and the distance of the injector from the axial center is adjustable. This is a device used for a new chromatography method that is characterized by the following features:

Jin's device has bar-shaped developing elements radially arranged around the axis, and the shaft or load injector rotates around the axis, so multiple developing elements can be loaded with expanded samples in succession. At this time, by setting the axis or the rotation angle of the injector to a constant value, the positioning of the sample load and the load operation can be automated. Further, the distance between the injector and the axis can be freely adjusted, and the developed sample can be loaded at a desired position on the developing element attached in the radial direction of the axis.

FIG. 1 shows an example of one embodiment of this device. This apparatus is equipped with a vertical rotating shaft 2 fixed on a substrate 1 and a load injector 3 for a developed sample. A rotation pulse motor 4 is attached to the base end of the rotating shaft 2 and can rotate around the axis, and there are fixing fittings 5 for the deployment element at the tip, and there are 8 pieces with a diameter of 1111 m and a length. 10 cm rod-shaped deployable elements 6 can be attached at intervals of 45 in the radial direction in the horizontal plane, and the attached elements 6 can be rotated about the axial center as the axis rotates. It is attached to the tip of an arm 8 that extends horizontally from the tip of the upright column 7 toward the two rotational axes.
can be moved horizontally by turning the adjustment knob 9 to freely adjust the distance between the injector 3 and the two central axes, and can be fixed close to above the sample loading position of the developing element.

In order to load a developed sample onto the developing element with this device, the rotating shaft 2Ik is rotated and set so that the injector 3 is positioned directly above one of the developing elements B. The arm 8 is moved horizontally to position and fix the tip of the injector 3 directly above the expanded sample loading position.

Next, set the setting knob to 10ft and set the pulse motor to 4.
Set the rotation angle of 01 times to 45°. First, a sample is loaded from the injector 5 onto one developing element 6.

After loading, the operation button 11 is pressed to rotate the rotation shaft 3, that is, the element 6 by 45 degrees, and load the sample onto another element 6 again. This operation is repeated to sequentially load the eight elements 6 with the sample.

The indicator device shown in FIG. 2 is also an example of the embodiment. This device has an arm 13 at the tip of a shaft 12 to which six rod-shaped deployment elements 6 can be attached.
is movable horizontally, and there is an injector at the tip. The element ゛6 attached to this shaft does not rotate, and the arm 13 provided at the tip of the shaft rotates around the axis 12 by a pulse motor 14 attached to the lower end of the shaft 12, and the injector 6 is rotated around the axis 12. Can be rotated around. Therefore, by setting the pulse motor 14 at 60 revolutions at a time, six elements 6 can be loaded with developed samples one after another.

The rod-shaped deployable element referred to in the present invention is one in which a thin layer of an adsorbent or a distributing agent is provided on the surface of a long rod or tube support. The means for attaching a plurality of rod-shaped deployable elements to a shaft include a method of attaching a plurality of separate elements directly to the axis in a radial direction, or a method in which a plurality of elements are oriented in advance in a radial direction with one point as the center and the There is a method of attaching an integrated product to the shaft by welding or joining using a connector at a point, and any method may be used.

The invention is as described above, and it is possible to automate the sample loading operation by automating the rotation of a plurality of rod-shaped deployment elements or injectors.
