Description

  The present invention relates to an auxiliary device and a liquid chromatography system.

  A liquid chromatography device is a device that separates and analyzes components of a liquid sample using a solvent as a mobile phase by combining units such as a pump, a sample injection section, a column, and a detector. In the liquid chromatography apparatus, each unit is vertically stacked from the viewpoint of space saving or the like (for example, see Patent Document 1). When each unit is stacked vertically, the solvent container is typically placed on top. This is because when the pressure of the pump is weak, it is difficult to send the solvent to the column if the solvent container is below the pump.

Japanese Patent Laid-Open No. 06-102269

  In this way, the solvent container is placed at the top of the apparatus, ie at the highest position. Conventionally, an operator has been working with a container placed at a high position in hand. However, installing the container at a high position is a troublesome work for the operator, and the work efficiency is lowered. Also, considering that toxic solvents may be used, this task is by no means desirable for worker safety. For this reason, at present, it cannot be said that separation analysis using a liquid chromatography apparatus is performed with high workability.

  On the other hand, it has been reported that in the case of a major earthquake such as the Great East Japan Earthquake, each unit stacked vertically collapsed, causing enormous damage. Therefore, it is an urgent task to provide the liquid chromatography apparatus with an earthquake resistant structure against such an earthquake.

  This invention is made | formed in view of the said situation, and it aims at providing the auxiliary | assistant apparatus and liquid chromatography system which can improve workability | operativity and earthquake resistance.

In order to achieve the above object, an auxiliary device according to the first aspect of the present invention provides:
An auxiliary device for assisting a liquid chromatography apparatus configured by stacking a plurality of units vertically,
A base plate on which the liquid chromatography apparatus is installed;
A column fixed to the base plate and having a height exceeding the liquid chromatography device;

A horizontal slider for moving the tray in a horizontal direction;
A controller that drives the vertical slider and the horizontal slider to control the position of the tray;
With
A fixing portion for fixing each unit is provided on the support column.

In this case, the support column is provided with a fastening portion that fastens each unit with a belt as the fixing portion.
It is good as well.

It is good as well.

Further, a slip stopper for the container is formed on the bottom surface of the tray.
It is good as well.

Moreover, the liquid chromatography system according to the second aspect of the present invention provides:
An auxiliary device of the present invention;
A liquid chromatography apparatus configured by vertically stacking a plurality of units;
Is provided.

  According to the present invention, since the solvent container can be automatically installed on top of the liquid chromatography apparatus, the work efficiency and work safety, that is, workability can be improved. In addition, since a plurality of units can be fixed to a support post fixed to a base plate on which they are installed, it is possible to prevent collapse of the stacking of each unit and improve earthquake resistance.

  Embodiments of the present invention will be described in detail with reference to the drawings.

  1 and 2 are perspective views of the auxiliary device 100 used in the liquid chromatography apparatus 150 according to the present embodiment. FIG. 1 shows only the auxiliary device 100, and FIG. 2 shows a liquid chromatography system 200 including the auxiliary device 100 and the liquid chromatography device 150.

  As shown in FIGS. 1 and 2, the auxiliary device 100 is a device that assists a liquid chromatography device 150 configured by vertically stacking a plurality of units.

  A liquid chromatography apparatus 150 is installed on the base plate 1. The base plate 1 is fixed, for example, by screwing on the surface of the work desk. This prevents the base plate 1 from moving on the surface due to an earthquake or the like. The base plate 1 may be installed on a floor surface or a shelf surface.

  The support column 2 extends in the vertical direction from the base plate 1. The support column 2 is fixed to the base plate 1 by welding or the like, for example. Thereby, it is prevented that the support | pillar 2 falls down by an earthquake etc. The column 2 has a height that exceeds the liquid chromatography device 150.

  The tray 3 accommodates a solvent container 15. Side walls are provided at the outer edge of the tray 3 to prevent the container 15 inside from falling off the tray 3. Further, a non-slip 20 for the container 15 is formed on the bottom surface of the tray 3.

  The vertical slider 4 is fixed to the column 2 by, for example, screwing or the like. A ball screw extending in the vertical direction is installed in the vertical slider 4. A member that moves in the vertical direction by driving the ball screw is connected to the horizontal slider 5.

  In the horizontal slider 5, a ball screw extending in the horizontal direction is installed. A member that moves laterally by driving the ball screw is connected to the tray 3.

  With the above configuration, the vertical slider 4 moves the tray 3 between the height of the base plate 1 and the height of the upper surface of the liquid chromatography apparatus 150. Further, the horizontal slider 5 moves the tray 3 in the horizontal direction.

  FIG. 3 shows a control system of the auxiliary device 100. As shown in FIG. 3, this control system is configured around a control unit 30. The control unit 30 controls the position of the tray 3 by driving the motor 11 of the vertical slider 4 and the motor 12 of the horizontal slider 5 via a driver circuit (not shown).

  The column 2 is provided with a belt fastening portion 21 for fixing each unit of the liquid chromatography apparatus 150 as a fixing portion.

  More specifically, the support column 2 is provided with a plurality of belt fastening portions 21 for fastening each unit of the liquid chromatography apparatus 150 with a belt. Each belt fastening portion 21 is provided for each unit. As shown in FIG. 4, the belt 23 holding each unit is fastened by the belt fastening portion 21, thereby preventing each unit from being shifted from the stacked state.

  The base plate 1 is formed with a rubber-like anti-slip 20 at a position facing the bottom surface of the lowermost unit. The anti-slip 20 engages the four legs of the unit, prevents the legs from shifting, and prevents the unit from moving laterally.

  Next, the operation of the auxiliary device 100 will be described. Here, a work procedure using the auxiliary device 100 will be described.

  As shown in FIG. 5, first, the tray 3 is positioned beside the liquid chromatography apparatus 150 and at the height of the base plate 1. In this state, the operator sets the solvent container 15. Since the container 15 is in a low position, the operator can easily perform the work.

  Subsequently, the control unit 30 drives the vertical slider 4 (drives the motor 11) to raise the tray 3 to the position shown in FIG. Further, the control unit 30 drives the horizontal slider 5 (drives the motor 12) to move the tray 3 to the position shown in FIG. Thus, the installation of the container 15 is completed, and analysis using the liquid chromatography apparatus 150 becomes possible.

  After the analysis is completed, the control unit 30 drives the horizontal slider 5 to move it from the position shown in FIG. 7 to the position shown in FIG. 6, and then the control unit 30 drives the vertical slider 4 to The position shown in FIG. 5 is moved to the position shown in FIG. At this position, the container 15 is easily removed.

  As described above in detail, according to the present embodiment, the solvent container 15 can be automatically installed on the upper part of the liquid chromatography apparatus 150, so that work efficiency and work safety, that is, workability is improved. Can be increased. Moreover, since a plurality of units can be fixed to the support column 2 fixed to the base plate 1 on which they are installed, it is possible to prevent the unit from being stacked and to improve the earthquake resistance.

  Specifically, each unit is fastened by a belt 23, and in particular, the bottom surface of the lowermost unit is also prevented from slipping and its lateral movement is restricted. Thereby, it is possible to fix all the units and prevent each unit from sliding down.

  An anti-slip 20 is also laid on the bottom surface of the tray 3 for storing the solvent container 15. Thus, the solvent container 15 can be prevented from falling over or falling off the tray 3.

  In the above embodiment, the vertical slider 4 and the horizontal slider 5 are configured by ball screws, but the present invention is not limited to this. For example, the vertical slider 4 and the horizontal slider 5 may be configured by linear motors.

  Further, each unit of the liquid chromatography apparatus 150 may be fixed to the support column 2 by screwing instead of a belt. Further, the base plate 1 and the lowermost unit may be screwed.

  Note that the height and width sizes of the liquid chromatography apparatus 150 vary depending on each manufacturer. It is desirable that the height of the column 2 and the strokes of the vertical slider 4 and the horizontal slider 5 be adapted to the sizes of the liquid chromatography apparatuses 150 of a plurality of manufacturers.

  Various embodiments and modifications can be made to the present invention without departing from the broad spirit and scope of the present invention. The above-described embodiments are for explaining the present invention and do not limit the scope of the present invention. In other words, the scope of the present invention is shown not by the embodiments but by the claims. Various modifications within the scope of the claims and within the scope of the equivalent invention are considered to be within the scope of the present invention.
