抄録

A microfluidic gas-intake device for measurement of gaseous substances was fabricated and tested. The gas-intake device has a window that provides direct absorption of gas into liquid in microchannels the membrane-type microfluidic device which uses a gas permeability of the PDMS membrane for gas-intake is fabricated and compared gas intake efficiency to the gas-intake device using the dissolution velocity of oxygen into D1 water channel. The degree of oxygen saturation was significantly improved (17.5 %) in case of the pillar-type device. This indicates that the pillar-type microstructure is effective for the gas-intake purpose.
