SURFACE PLASMON RESONANCE MEASURING SYSTEM AND A METHOD FOR SURFACE PLASMON RESONANCE MEASUREMENT

摘要

The invention relates to surface plasmon resonance (SPR) measuring system comprising: at least one sensor having at least one sensor surface; at least one flow cell which is in liquid contact with the sensor surface; an optical unit for measuring the surface plasmon resonance angle of light incidence at the sensor surface; sampling means for supplying at least a sample and a buffer separated by separation flu?dum into the flow cell; liquid transport means for liquid transport; and means for generating a back and forth flow of sample or buffer at the sensor surface, and to a SPR method.
