PURPOSE: A multi-channel surface plasmon resonance measure system using a beam profile ellipsometer is provided to measure a junctional characteristic and a dynamic characteristic of a biomass in real time by measuring plasmon resonance measurement and ellipsometer phase change according to an angular change and a location change by measuring a light amplitude and phase together. CONSTITUTION: A multi-channel surface plasmon resonance measure system using a beam profile ellipsometer comprises: a vertical incident focused-beam ellipse meter which polarizes light and measures the ellipse meter phase change by detecting the polarized light reflected with focusing the partial polarized light to a metallic foil(42) including a multi-channel from an object lens; a surface plasmon resonance sensor(40) which is arranged in the object lens of the focus-beam ellipse meter and generates a surface plasmon resonance by the angular variation of the polarized light; and a multi-channel flow path(1) which supplies buffer solution including the biomass which generates adsorption or desorption to the metallic foil. The surface plasmon resonance and the ellipse meter phase change by the angular variation and the wavelength change are detected at the same time.
