Our Surface Plasmon Resonance (SPR) Spectrometer enables us to perform highly-sensitive, non-label analysis for the interaction of chemical species (e.g. biological molecules) on a surface in real time by utilizing the surface plasmon resonance phenomena. Surface Plasmon excitation is achieved with a 633 nm HeNe laser, while a sensitive silicon detector senses the reflected light. Polarizers allow easy selection of p- or s-polarized light; the measurement cell is specifically optimized for small sample volume. The system is equipped with a Si photodiode detector paired with lock-in amplifier and goniometer (angular resolution 0.005o).
