    • A sample leaving a separation column of liquid chromatograph is led to an electrolytic cell to obtain an electrolytic current corresponding to the amount of an assayed sample component. The electrolytic cell is divided into two compartments by an ion exchange pipe penetrating therethrough at the center. One compartment is a cylindrical working electrode chamber in the pipe, and the other compartment is a cylindrical chamber for a counterelectrode outside the pipe. A working electrode comprising a bundle of electroconductive carbon fibers is provided in the working electrode chamber, and preferably a swellable rod is inserted as a core into the working electrode. In the chamber for the counterelectrode, a cylindrical counterelectrode made of carbon fibers is provided to surround the outside surface of the ion exchange pipe. The inner diameter of the ion exchange pipe is substantially equal to the inner diameter of a tube for introducing the sample. The sample undergoes electrolysis reaction while the sample passes through the carbon fibers of the working electrode.

    • An improved wet-laid nonwoven fabric for a battery separator wherein 20 to 95% by weight of thermoplastic staple fibers having a single fiber diameter of 20 .mu.rm, or less are three-dimensionally entangled with hot-melt fibers having a melting point lower by 20.degree. C. than that of the thermoplastic staple fibers so that a mean fiber entangling point interval is 300 .mu.m or less, wherein at least part of the hot-melt fibers are fused to bond the fibers with each other to fix the nonwoven structure. The nonwoven fabric has a basis weight in a range from 10 to 350 g/m.sup.2, a thickness in a range from 30 to 1000 .mu.m and an apparent density in a range from 0.26 to 0.7 g/cm.sup.3, and is excellent in uniformity and mechanical strength. The wet-laid nonwoven fabric is particularly excellent in air permeability, liquid holding capability, liquid retention capability and liquid absorption rate and satisfies the requirement for a battery separator. Therefore, it is useful for the production of a high performance secondary battery having favorable overcharging characteristics and cycle characteristics. The wet-laid nonwoven fabric according to the present invention is prepared by subjecting a wet-laid web of staple fibers having a ratio L/D of a fiber length L to a single diameter D in a range from 0.5.times.10.sup.3 to 2.0.times.10.sup.3 to a hydroentangling treatment while taking care not to leave a mark from a water jet on the web.
