In general, the chemical is supplied to the main storage tank through a tank lorry, etc., and a part of the chemical stored in the main storage tank is divided and stored in a plurality of sub storage tanks, so that it is sequentially supplied to one unit process or individually to a plurality of unit processes can be supplied.

As another example, if there is a small amount of chemicals or if a tank lorry cannot be used due to the nature of the chemical itself, it may be directly supplied to the sub storage tank through a drum, a bottle, or the like.

If chemicals are contaminated in tank lorries, drums, bottles, storage tanks, pipes, etc., defects may occur in the unit process that receives them.

Therefore, the degree of chemical contamination needs to be managed at an appropriate level for each major location such as a tank lorry, drum, bottle, storage tank, and piping, and accordingly, a sampling device capable of sampling chemicals at major locations has been developed.

A conventional sampling apparatus includes a sampling booth, a plurality of sampling lines respectively connected to a plurality of main positions to supply chemicals to sampling bottles accommodated in the sampling booth, and valves respectively installed in the plurality of sampling lines.

The operator was able to perform the sampling operation as follows using a conventional sampling device.

For example, the operator directly opens the cap of the sampling bottle and puts the sampling bottle into the sampling booth, operates the valve on the sampling line connected to the main location to be sampled, and fills the sampling bottle with chemicals, and puts the chemical-filled sampling bottle into the sampling booth. After collection, the sampling bottle was directly closed and transported to the chemical contamination analysis site.

As described above, most of the sampling work was generally performed manually by an operator.

Therefore, there is a problem that there is a high possibility that chemical contamination occurs due to negligence of the operator during the sampling operation, and there is also a problem that the operator is highly likely to be exposed to chemicals.

These problems are particularly likely to occur when the operator opens and closes the lid of the sampling bottle.

On the other hand, when chemical contamination occurs during the sampling operation, the reliability of the chemical contamination level analysis result may be reduced. In addition, for worker protection, the inconvenience of preparing, wearing, and taking off safety equipment of the highest level of protection may occur.
