    Abstract: PURPOSE:To provide a recording medium having high durability by interposing a required gas barrier film between a carbon substrate and a recording layer. CONSTITUTION:A recording medium is composed of a carbon substrate made of vitreous carbon and a recording layer, and a gas barrier film of SiO2, SiO, Si3N4, ZrO2, ITO, Ta2O5, a composite material of them, etc., is interposed between the carbon substrate and the recording layer. Even when the carbon substrate is set in an atmosphere at a high temp. in order to form a magnetic film on the substrate, gaseous impurities generated from the carbon substrate owing to unsatisfactory carbonization do not diffuse into the magnetic film by the presence of the gas barrier film and the objective recording medium having high durability is obtd.

    Abstract: PURPOSE:To achieve higher quality by building an electroconductive layer based on a pi conjugate structure on the surface of an organic protective film. CONSTITUTION:An ultraviolet hardening type hard coating agent is applied on a polycarbonate substrate 2 at a thickness of 1-20 mum by a spin coat method and hardened by irradiation with ultraviolet rays to form an organic protective film 3. The substrate 2 is allowed to stand in a pyrole monomer vapor for two hours. Thereafter, it is immersed into a 10% ferrous methanol chloride solution and washed by water sufficiently after one hour to make a electroconductive layer 4 based on a pi conjugate structure. This makes the product hard to damage and achieves higher quality with limited adhesion of dirt and dust and limited generation of errors.

    Abstract: PURPOSE:To improve the stability of a base current in a carbon electrode and thereby to improve the precision in analysis and reproducibility, by a method wherein the density and the size of an opening existing in a working electrode are set at specified values. CONSTITUTION:A sample liquid to be quantified is supplied from a high-speed liquid chromatography 1 into an introduction port 2, made to contact with a working electrode 4 covered with a Teflon seal 3, made further to contact with a reference electrode 5 and then discharged from a discharge port 7 to which an auxiliary electrode 6 is fitted. Between the working electrode 4 and the reference electrode 5 a voltage is impressed from a power source 8. A current value of the working electrode 4 is relation to the eluation volume of the sample liquid passing from the introduction port 2 to the discharge port 7 is measured for analysis by a current measuring device 9. Besides, the working electroe 4 has openings whose density is 2X10 /mm bellow and whose maximum diameter is 0.5mum or below, and it is formed of an isotropic carbon material. By using a surface-polished vitreous carbon material as this carbon material, S/N can be improved and thus a stable analysis can be attained.
