Abstract

A method for determining a liquid-soluble gas such as ammonia with satisfactory reproducibility and high sensitivity; a method for gas-liquid phase separation for use in that method; and a microchannel chip for the methods. The microchannel chip is equipped with: a microchannel formed in a substrate; and a gas-liquid phase separation microchannel connected to the downstream end of the microchannel and having a depth of 10-100 µm, the top of the separation microchannel being covered with a porous film. The gas-liquid phase separation method is a method in which a two-phase flow consisting of a gas phase and a liquid phase passes through the microchannel, the liquid-phase flow passing through a peripheral portion of the microchannel and the gas-phase flow passing inside the peripheral portion, and the gas phase is removed from the two-phase flow to leave the liquid-phase flow. The method involves: passing the two-phase flow through the microchannel within the microchannel chip; leading the flow to the gas-liquid phase separation microchannel; passing the flow through this region; and thereby discharging the gas-phase flow outside from the gas-liquid phase separation microchannel through the porous film.

Also disclosed is a stirring apparatus for the method. The method, which is for hydrolyzing a polysaccharide with a solid acid catalyst, comprises conducting a hydrolysis reaction under such conditions that water is used in an amount smaller than that corresponding to the proportion of the solid acid catalyst to the water, i.e., (solid acid catalyst): water, of 3:7 by weight. The stirring apparatus for the method comprises a vessel and a stirrer disposed in the vessel. The stirrer comprises a rotating shaft which is rotatable and platy stirring blades fixed to the rotating shaft. These stirring blades have been disposed in stages apart from each other in the axial direction for the rotating shaft.

Abstract

Provided is a micro chip which can integrate a liquid phase evaporation as an operation on the micro chip. A micro chip (10) has a gas phase channel (13) inside the micro chip. A liquid phase is dispersed into a pool portion (12) at the bottom of the channel (13) by using the capillary force and the dispersed liquid phase is pooled so that at least a part of the liquid phase pooled in the pool portion (12) is evaporated. By using the capillary force, it is possible to disperse the liquid phase into the pool portion (12) at the bottom of the channel (13) in the micro chip (10). Besides, even if a gas phase flows into the channel (13) because of the evaporation or the channel is evacuated, the liquid phase pooled in the pool portion (12) remains in the pool portion (12) by the surface tension. Thus, it is possible to realize a highly effective evaporation operation in the micro chip (10).

Abstract

Pores of an anodized porous alumina having a porous surface structure are filled with a material and then the anodized porous alumina is dissolved and removed, thereby forming a stamper which is made of the material and has a reverse structure of the surface structure of the alumina. By transferring the reverse structure of the stamper to a polymer, there is produced a porous polymer membrane having the surface structure of the alumina. Consequently, a large-sized porous polymer membrane having a surface structure, wherein pores of a uniform size are formed orthogonal to the membrane surface, can be produced without requiring a complicated process.
