Reichert Inc.'s entry into the design and manufacturing of Surface Plasmon Resonance (SPR) instrumentation began with collaboration between Leica Microsystems (Reichert Inc. predecessor) and Cornell University starting in mid-1997. This collaboration spearheaded efforts to incorporate biosensing technology into Reichert's core critical angle refractometer products. This technology built upon a key Reichert Patent (US Patent #4,640,616, Automated Refractometer, 1987) describing a digital reflected light refractometer incorporating a charge coupled device to sense reflected light intensity over a range of angles covering a refractive index range from 1.33 to 1.52.
Basic technology described in this patent was utilized to construct Reichert's first single channel SPR device, the SR6000, first sold in 2000. A subsequent version, the SR7000 introduced in early 2003, incorporated features such as greatly improved signal to noise, lower volume fluidics and electronic temperature control.
In mid-2006, Reichert Inc. introduced and began selling a two channel SPR Spectrometer, the SR7000DC. This instrument features two channels (experimental and reference) improved signal to noise, lower baseline drift, and vastly improved optics, electronics and computing power.
