Abstract

PURPOSE:To integrally form an eluate storage tank, sepn. column and flow cell on a silicon semiconductor substrate by utilizing the force generated by the powerful magnetic field generated by a superconductive electromagnet and the current flowing orthogonally therewith as means for feeding an eluate (carrier). CONSTITUTION:A flow passage 11 of micron order is formed on the semiconductor substrate. An eluate reservoir 12 and a specimen reservoir 13 are provided at one end thereof and a discharge port 14 in common use as the flow cell for detecting the concn. or activity of the solute in the eluate is provided to the other one end. A pair of electrodes 21 are provided to the flow passage perpendicularly to the substrate plane and a voltage is impressed to the electrode 21 when the eluate arrives at this point. A high magnetic field is previously applied on the semiconductor substrate 1 to generate the force F as the ions in the eluate between the electrodes migrate. This force acts on the eluate so that the eluate moves in the flow passage. The sepn. column of the liquid chromatograph and the eluate feed means are thus connected without using any special mechanical mechanism.
