Composition and method for manufacturing ion selective electrode sensors

This invention pertains to fluorophoric compositions of a 7-amino-coumarin derivative and methods of their use for enhancing visualization of various constituents of ion selective electrodes.

A readily disposable ion selective electrode assembly, free of onboard reagents, for use in analyzers has a reference element and plural sensor elements linearly positioned in parallel on a substrate. An elastomeric flow channel member containing two parallel grooves creates flow channels on the substrate above the elements. The substrate holds the elastomer in compression and is retained by snaps injection molded into a housing. Electrical contacts and leakfree fluidic connections are provided by spring loaded connectors through the housing. Reference and sample fluids are drawn through the respective flow channels and come together to form a liquid junction downstream from the sensor elements. Bubbles, that might otherwise cause erroneous results, are detected.

A fiber optic device is provided with a feedthrough assembly adapted to decouple deflections imposed on the feedthrough from lensed end of a fiber disposed within the feedthrough assembly.

Decoupled fiber optic feedthrough assembly

An optical transmitter assembly (1) comprises an optical source (20) and an optical detector (20) arranged to receive light output from the source (10) indirectly via a reflector (30). The source (10), the detector (20), and the reflector (30) are mounted on a common support structure (40). A unitized light reflector assembly (70) having the reflector (30) and detector (20) on a ceramic plate (72) is also disclosed.
