Abstract: An apparatus as provided for use in carrying out electrochemiluminescence test measurements. The apparatus includes a fluid container having an inlet for introducing an electrochemiluminescence sample fluid and a fluid outlet. The fluid container is composed of a durable, transparent, chemically inert, and electrically nonconductive material. A working electrode is disposed to one side of a fluid flow path of the container which has a light transmissive wall opposite the working electrode. A counter electrode is secured to the light transmissive wall. A first portion of the counter electrode is disposed upstream of the working electrode, while a second portion of the counter electrode is disposed downstream of the working electrode.

Abstract: An apparatus is taught for carrying out electrochemiluminescent measurements which includes a working electrode and a temperature sensor. The electrochemiluminescent measurements made by the apparatus are adjusted based upon the measured temperature.

Abstract: A shaft extending in the skating directions is supported by stanchions depending from a boot plate. Spherical wheels formed by hemispherical segments are rotatably secured to the shaft in fixed axial position by a ring member having wing axles extending transversely the shaft axis, the ring member being rotatable about bearing members secured to the shaft. One Of the bearing members has a braking cam with a pair of oppositely positioned recesses which mate with a corresponding braking detent mechanism mounted in each wing axle. Each wheel segment is independently rotatably secured to a wing axle for rotation in the skating directions. The wing axles rotate with the wheels about the shaft in response to a stopping action transverse to the skating directions to provide a braking resistance in response to the detent mechanism riding against the cam surface. Different spring loads and springs are provided to allow for different skating stroke and stopping forces.
