ABSTRACT:
A method for linear filtering of noise in a SPR sensorgram generated from a surface plasmon resonance apparatus is provided. The method includes providing a linear filter of variable length to filter an output signal in the sensorgram. The method further includes determining an optimal length of the linear filter based on a slope of the signal in the sensorgram and multiple timing of occurrences of events during measurement of refractive index in the apparatus to reduce noise in the sensorgram.
