Judging on the literature many of you are struggling to get nice sensorgrams with easy to fit curves. However, SPR is straightforward when you know what you are doing. Consequently, you have to learn how SPR works, how to perform an experiment and how to analyze it.
Total internal reflection When a light beam hits a half circular prism, the light is bent towards the plane of interface, when it is passing from a denser medium to a less dense one. Also known as surface plasmon resonance microscopy, SPRi follows the same general principles of SPR. However, the information that is measured and the method of detection is different. This technique was inspired by the need for a higher-throughput method of studying binding interactions that exploits the phenomenon of surface plasmon resonance. 2 Surface plasmon resonance (SPR) can be used to analyze both binding affinities and kinetic parameters between a ligand and an analyte. SPR can be performed by either cross-linking a given ligand to a sensor chip covalently or utilizing high-affinity non-covalent interactions to secure a ligand in a particular conformation to a chip, both of which have their potential advantages. The simultaneous measurement of surface plasmon resonance (SPR) spectroscopy and surface-enhanced Raman scattering (SERS) on flat metallic surfaces is demonstrated on a relatively simple experimental setup based on the Kretschmann configuration.
“Surface Plasmon resonance” refers to the coherent oscillation of the electrons at the interface of a metal and a dielectric when the metal subjected to an incident light.” The incident radiation gives rise to a surface wave with specific optical properties. CONDITIONS FOR SPR:

The method allows to characterize a broad spectrum of interactions.
When the transversal magnetic (TM) incident fading wave phase velocity matches with the phase velocity of SPs, the surface plasmon resonance (SPR) phenomenon occurs. Moreover, all incident photon energy will shift to SPs 3].
