摘要： A flow cell for fiber optics spectroscopy having a radiation transparent window for the transmission of radiation uses a dual O-ring arrangement to prevent leakage of a medium undergoing evaluation around the window and a vent for indicating leakage between the O-rings. The arrangement also provides for the use of an O-ring to urge the window against a retainer that holds a lens to direct radiation into the window. Biasing of the window against the lens retainer and the use of a radial O-ring arrangement allows precise control of the separation between windows in the total path length for radiation travel across a fluid sample.

摘要： A system for processing a specimen to which fluid must be added includes a fluid dispensing work station within a housing. The work station holds the fluids that are to be added to the specimen. A nozzle dispenses fluid at the work station. The system also includes a carrier that moves within the housing. The carrier operates in a first mode at the fluid dispensing work station. The carrier also operates in a second mode outside the work station to perform a different processing function. A coupling mechanism attaches the nozzle to the carrier when the carrier enters its first operational mode to transport the nozzle around the fluid dispensing station. The coupling mechanism releases the nozzle from the carrier when the carrier enters its second operational mode, thereby freeing the carrier for movement outside the work station out of association with the nozzle.

摘要： A probe for fiber optic spectroscopy, having a radiation transparent window for the emission of radiation and an optical fiber that extends through the interior of a hollow housing, surrounds the fiber with a cushioning sleeve to provide an optical cable that preserves optical fiber connections and dampen vibration of the optical cable. The sleeve provides a structure around the optical fiber that is more compressible than the optical fiber and has a significantly greater mass than the optical fiber. Excess cable length may be provided along its path through the housing to impinge the cable against the interior walls of the housing and thereby dampen vibration by providing additional node points through contact of the sleeve with the housing wall. Helical twisting of the cable along its path through the housing further stabilizes the shape of the fiber optic cable within the housing and maintains a regular spacing of contact points with the housing. Regular spacing of node points consistently controls vibration dampening by contact between the housing wall and the cable.
