In the present study, oxygen transfer process across gas-liquid interface in a Y-shape microchannel is quantitatively visualized using the micro laser induced fluorescence (μ-LIF) technique. Diffusion coefficient of Oxygen (D<SUB>L</SUB>) is estimated based on the experimental results and compared to its theoretical value. Tris ruthenium (II) chloride hexahydrate was used as the oxygen quenchable fluorescent dye. A light-emitting diode (LED) with wavelength of 450 nm was used as the light source and phosphorescence images of fluorescent dye were captured by a CMOS high speed camera installed on the microscope system. Water having dissolved oxygen (DO) value of 0% and pure oxygen gas were injected into the Y-shaped microchannel by using a double loading syringe pump. In-situ pixel-by-pixel calibration was carried out to obtain Stern-Volmer plots over whole flow field. Instantaneous DO concentration fields were successfully mapped according to Stern-Volmer plots and DL was calculated as 2.0675×10<SUP>-9</SUP> m<SUP>2</SUP>/s.
