Abstract: A solid type nano-pore sequencer is arrayed easily. In a liquid column separation device including first and second base materials, a liquid feeding unit supplies fluids to a gap between the two base materials. Hydrophilic and hydrophobic regions are disposed on a surface of the second base material, and the hydrophilic region is disposed to oppose a predetermined position of the first base material where a substance to be measured is made to pass through. Also, a flow passage space includes at least one inlet and outlet through which fluids can flow in and out. A representative length of the hydrophilic region is made larger than a distance between the first and second base materials, and thereby a liquid column capable of connecting the first base material and the second base material is formed by making two or more immiscible fluids to flow by the liquid feed unit.

Abstract: A control method, for a transaction management server of a transaction administrator administrating commodity transactions between a seller and a buyer, comprises transmitting to a forwarder terminal an instruction to transport a commodity received along with price information of the commodity from a seller terminal; writing the price information into a database; receiving from the forwarder terminal and writing into the database the number of the waybill issued when the commodity is loaded into transportation by the forwarder; transmitting to the seller terminal information indicating that the transaction administrator has made an alternative payment for the commodity; receiving from the forwarder terminal and writing into the database the number of the waybill put on the commodity having arrived at a destination and commodity identification information; receiving the commodity identification information of the commodity delivered to the buyer from the forwarder terminal, and transmitting to a buyer terminal
