摘要
A device and method for producing data for correction curves for SPR assays provides a plurality of different concentrations of solvent or other compound to the reference surface and active surface of a SPR chip. The concentration are mixed online by two pumps, one connected to a source of a first concentration of solvent or other compound and the other connected to a source of a second, different concentration of solvent or compound. Mixing of the two different concentration of solvent or compound can take place in a fluid mixer and the concentration of solvent or compound in the mixture leaving the fluid mixer can be varied by adjusting the relative speeds of the pumps. The concentration of the solvent or compound mixture can be adjusted during injection of the mixed liquids in order to provide the different concentrations necessary to make a solvent correction curve.
