The application of tubular liquid membrane to an ethanol sensing device was tried using FIA. The membrane was formed by impregnating methyl hydrogene polysiloxan (MHPS) in the porous wall of a ceramic tube. When the tube containing water was immersed in an aqueous ethanol solution, the ethanol dissolved in MHPS and diffused into the water, forming a radial gradient of ethanol concentration. A Baser beam transmitted through the tube was expanded by concave-lens effect. The drop in power density of the transmitted beam was roughly correlated with the ethanol concentration. However, reprodudbility of data was unsatisfactory, possibly due to disturbance of the boundary between the ethanol solution and carrier water.
