An instrument for total internal reflection fluorescence spectroscopy having modular probe that inexpensively monitors vapors and liquid-phase analytes under field conditions is described. The system is particularly helpful in evaluating multiple analytes using the fluorescence of a material immobilized in a thin sorbent polymer coating. At the same time, the system is capable of monitoring trace quantities of analyte using a fluorescence-read immunological reaction. The device includes a diode laser source, a shaped optical element (which may be as simple as a microscope slide), and one or more amplified photodiode detectors. The shaped optical element propagates light from the diode laser in a series of internally reflective bounces.

Modular probe for total internal reflection fluorescence spectroscopy

A short boat motor transmission is presented that is less than five inches wide. The main parts of the transmission includes a high clutch drum which contains a Belleville spring, an input ring gear and clutch plates secured at the top by a pressure containment ring and snap-ring. The input ring gear is connected directly to the motor. This ring gear is also connected to a pinion carrier and four pinion planetary gears. The output shaft of the transmission is attached to the pinion carrier. The planetary gears in the pinion carrier are connected to the inner teeth of the input ring gear and to a sun gear. The outer part of the pinion carrier may also be mechanically connected in locked position to the input ring gear by clutch plates. The sun gear is connected to a one-way locking mechanism which only allows the gear to turn in one direction. Since all of the centers of the various parts are in alignment and since the various parts are nested the transmission is very short. When the piston carrier and input ring gear are connected together by the clutch plates, the transmission is in high gear. When the pinion carrier and input ring gear are not so connected, the transmission is in low gear.
