High pressure flow-through cuvette

Abstract

Abstract A CUVETTE FOR MONITORING A FLOWING LIQUID STREAM INCLUDING A FLOW CELL ASSEMBLY ENCLOSED WITHIN A LIGHT OPAQUE HOUSING. THE FLOW CELL ASSEMBLY INCLUDES A SLENDER OR NARROW GASKET MEMBER HAVING AN OVAL SHAPED APERTURE FORMED THEREIN SANDWICHED BETWEEN A PAIR OF LIGHT TRANSPARENT PLATES. THE APERTURE FORMED IN THE GASKET MEMBER IS LINED BY AN O-RING SEAL AND BONDED ON EITHER SIDE BY THE INNER FACE OF EACH PLATE TO DEFINE AN ANALYZING CHAMBER HAVING A SUFFICIENTLY SMALL CROSS-SECTION OR THICKNESS TO PERMIT A RELATIVE VISCOUS LIQUID STREAM TO FREELY FLOW THROUGH THE CHAMBER WITHOUT ANY DANGER OF TURBULENCE OR TRAPPING OF AIR BUBBLES CONTAINED IN THE STREAM. ONE OF THE TRANSPARENT PLATES INCLUDES INLET AND OUTLET PASSAGEWAYS COMMUNICATING WITH THE ANALYZING CHAMBER THROUGH WHICH THE LIQUID STREAM IS CONTINUOUSLY FED INTO AND REMOVED FROM THE CHAMBER. THE HOUSING SERVES TO CLAMP OR TIGHTLY HOLD THE SLENDER GASKET FIRMLY BETWEEN THE PAIR OF TRANSPARENT PLATES AND IS PROVIDED WITH A PAIR OF APERTURES AXIALLY ALIGNED WITH EACH OTHER AND THE FLOW CELL ASSEMBLY TO PROVIDE A LIGHT PATH ORTHOGONAL TO THE DIRECTION OF LIQUID FLOW ALONG WHICH A LIGHT BEAM OF A SELECTED WAVELENGTH IS TRANSMITTED.
