[0017] The elastic support pad of this utility model includes a support plate adapted to the placement groove. A first spring is provided between the support plate and the bottom of the placement groove. The support plate is adapted to the size of the placement groove. Through the extension and contraction of the first spring, the support plate can move vertically up and down to cooperate with the vertical buffering of the solid phase extraction column and prevent damage to the solid phase extraction column.

[0018] The support plate has a through hole that corresponds to the interface of the solid-phase extraction column. During use, the interface can extend downwards into the through hole, minimizing the risk of damage.

[0019] The upper surface of the support plate is provided with several anti-slip protrusions, which makes the column less prone to displacement or shaking, and provides a good fixing effect.

[0020] The bottom of the placement box is equipped with shock-absorbing pads to reduce vibrations experienced by the placement device during handling or placement, thus preventing damage to the solid-phase extraction column. The shock-absorbing pads are made of rubber material, which has good elasticity and wear resistance.

[0021] The lower part of the placement slot is provided with a desiccant placement chamber, and the top of the desiccant placement chamber is provided with several ventilation holes to prevent moisture from entering the placement box. At the same time, the side of the desiccant placement chamber is provided with an openable sealing door for easy replacement of the desiccant.

[0022] Both the first and second elastic claws include a support rod. A sleeve rod is slidably fitted onto the outer side of the support rod. A second spring, adapted to one end of the sleeve rod, is provided on the outer side of the support rod. A fixing claw is provided at the other end of the sleeve rod. By compressing the second spring, the solid-phase extraction column can be easily placed and removed. At the same time, the second spring and the fixing claw can more stably clamp and fix the solid-phase extraction column, resulting in good performance.

[0023] The fixing claw includes a first clamping plate arranged horizontally and a second clamping plate arranged vertically, both of which are arc-shaped. The cross-shaped fixing claw provides better fixation for the solid-phase extraction column and reduces the likelihood of shaking during transport.

[0024] The two sides of the placement box are respectively equipped with classification label plates adapted to several placement slots. Each classification label plate has a replaceable label, and each label corresponds to a storage slot, used to mark the type, specifications and other information of the solid phase extraction column in the storage slot, so as to facilitate quick search by operators.

[0025] The two sides of the placement box are respectively provided with expiration date display windows adapted to the placement slot, which can clearly display the expiration date information of each solid phase extraction column, facilitating timely management and use.
