DIFFERENTIAL PLANE-PARALLEL FLOW-THROUGH TRAY Russian patent published in 1997 - IPC

FIELD: liquid chromatography. SUBSTANCE: tray two airtight, adjacent, hollow, transparent, prismatic compartments with common main section, inclined plane-parallel transparent partition common to prismatic compartments and positioned at sharp refracting angle to input and output edges of compartments, and two casings with flow-through channels for delivery and removal of liquid. Casings are made in the form of prisms with common main section and equal refracting angles between hypotenuse and input and output edges of casings in which translucent cylindrical channels are made. Axes of channels continue each other reciprocally. They are positioned normally to input and output edges of prismatic casings. Plane-parallel transparent partition is installed tightly between adjacent hypotenuse edges and hypotenuse faces of translucent cylindrical channels. Plane-parallel transparent sealing glasses are arranged tightly in translucent cylindrical channels till they rest on the above-indicated partition. Outlets of delivery channels are positioned opposite to inlets of removing channels between transparent partition and sealing glasses. Centers of outlets of delivery channels and Centers of inlets of removing channels are located in plane perpendicular to plane of tray main section. EFFECT: higher results of analysis. 3 dwg
