The present invention relates to a sealed high-density on-line measuring device for spectrophotometer whose cuvette holder is linked to a reactor, which comprises a base; a fixed plate for light passage, which is vertically placed on the base; a moving plate for light radiation, which is vertically placed on the base at an opposite side to the fixed plate so that it can slide on the base horizontally; inlet and outlet for sample passage, each of which is positioned at outer side of the moving plate; a metal ring linking the fixed plate and the moving plate; and, upper and lower shielders each of whose ends is in contact with the fixed plate and moving plate, respectively, to give a sealed space. In accordance with the scaled on-line measuring device of the invention, high concentrations of samples in solutions can be measured without dilution, by way of employing a newly designed cuvette holder in a spectrophotometer fitted to a reactor.

Sealed high-density on-line measuring device

The present invention provides for a method for manufacturing a field emitter array comprising the steps of depositing a silicon nitride mask pattern layer on the silicon substrate, forming a porous silicon layer in the substrate except in parts under the nitride mask patterns and oxidizing the porous silicon layer and the silicon substrate under the silicon layer, which results in formation of cone shape cathode tips. Further, gates corresponding to said cathode tips are provided by the conventional process or by process of depositing thin metal film and photoresist on the mask patterns and the porous silicon layer, etching the photoresist layer on the patterns, and then etching the metal film on the patterns, or by lift-off process.
