Patent Number Title Of Patent Date Issued
4045343 High pressure liquid chromatography system August 30, 1977
A high pressure liquid chromatography system including a reservoir for a liquid mobile phase, an LC column and detector, a high pressure reciprocating pump for enabling flow from said reservoir through the column, and a positively actuated inlet valve for controlling flow from the re
4032445 Liquid chromatography pumping system with compensation means for liquid compressibility June 28, 1977
In a liquid chromatography system including a chromatographic column, a reservoir for a slightly compressible liquid mobile phase, piston means cooperating with the reservoir for pumping the liquid phase through the chromatographic column, and means for displacing the piston at a pre
4006990 Convergent light illuminated flow cell for liquid chromatography February 8, 1977
Single and dual beam flow cells for liquid chromatography that provide good detectability and linear response with small sample volumes. A cylindrical window surrounds the sample flow path to permit focusing convergent light rays through the center of the flow path and along optical path
3999439 High pressure sample injector and injection method December 28, 1976
An injection apparatus and method for use in high pressure liquid chromatography. A cylindrical sample holding means containing several sample cells is maintained in a chamber whose pressure is approximately equal to that of the head of the chromatograph separation column. The sample
3985019 Liquid chromatography system with solvent proportioning October 12, 1976
A liquid chromatography system including a liquid chromatography column, first and second reservoirs for solvents to be utilized as the mobile phase, reciprocating pumping means for flowing the solvents through the column, and motor means for driving the pump through successive pumping
3975104 Convergent light illuminated flow cell for liquid chromatography August 17, 1976
Single and dual beam flow cells for liquid chromatography that provide good detectability and linear response with small sample volumes. A cylindrical window surrounds the sample flow path to permit focusing convergent light rays through the center of the flow path and along optical path
3950104 Refractive index and flow rate detector and method April 13, 1976
Apparatus and method for detecting the refractive index and rate of fluid flowing through an elongated flow cell, having applications in liquid chromatography. The cell may be of circular cross section and has an input window in one end, an exit window in the other, and a longitudinal si
3934456 Solvent gradient generator for chromatography systems January 27, 1976
Solvent gradient generating apparatus in a liquid column chromatography system. A multi-compartment vessel having an input/output port pair for each compartment is coupled between a high pressure pump and the column cell for providing both gradient generation and pulse damping. A piston,
3930399 Viscosity detection apparatus and method January 6, 1976
Apparatus and method applicable to liquid chromatography for continuously detecting the viscosity of the effluent from an analysis column of a chromatograph system. The effluent is forced through a tubular path in a flow resistance element, which may contain a packing material to increas
