The invention relates to a surface plasmon resonance system method. The system has at least one light source operable to generate a source beam, a prism having a rear surface at least partially coated with a metallic coating and optionally a dielectric layer. At least one layer under test is positioned on the rear surface of the prism. The source beam is directed at the layer under test thereby defining an angle between the source beam and the rear surface of the prism. A detector is operable to detect light that is reflected or scattered by the layer under test. The source beam is directed towards the layer under test at a selected angle. The source beam is also shifted in at least one plane to illuminate a specific portion of the layer under test based on the selected relative angle and the position of the layer under test on the rear surface of the prism. The rear surface of the prism can be illuminated in one-dimensional or two-dimensional array like fashion.

Beam shifting surface plasmon resonance system and method

A trailer with wheels located near its rearward end and a connecting arm extending from a mid-region of the forward end of the trailer. The connecting arm includes a gooseneck with a ball receptacle to connect with a ball protruding upwardly from the truck bed. A shroud is connected to the forward end of the trailer beneath the connecting arm and a powered hydraulic cylinder is carried inside the shroud and includes a rod extending downwardly to raise and lower the front of the trailer. A stabilizer arm terminating in a foot portion is carried by the shroud to extend downwardly and co-extensively with the rod to protect the hydraulic cylinder and rod from loading other than by the weight of the trailer and its load.
