Patent Number Title Of Patent Date Issued
5804142 Chromatograph system and method for maintaining system suitability thereof September 8, 1998
A reference sample having a known concentration is injected into a chromatograph system before an unknown sample is analyzed. This is for the purpose of checking the deterioration of system performance or in other words for the purpose of checking system suitability. In the present i
5783450 Analytical method and instrument for analysis of liquid sample by liquid chromatography July 21, 1998
A method and an instrument for separating and analyzing a very small quantity of constituents to be inspected contained in an analyte such as a class of catecholamines by liquid chromatography after labeling. The entire processes of analytical operations include principally three pro
5670379 Chromatograph system and method of use September 23, 1997
A chromatograph system with improved automation is provided. In the chromatograph system of one embodiment, a regression line is set between retention times of predetermined peaks measured at each run in the past for a standard sample having known components. Referring to this regres
5436166 Method of and apparatus for performing chromatography analysis of unknown sample July 25, 1995
The present invention relates to a chromatography analysis method and a system employing the same which are capable of automatically determining an constituents to be detected contained in the unknown sample based on results on measuring a standard sample. The standard sample is first
5308774 Liquid chromatographic method and apparatus for analyzing biological samples May 3, 1994
Physiologically active substances contained in a biological sample not subjected to deproteinization can be converted to their derivatives at a high efficiency without being adversely affected by the protein present in the sample, and accordingly the analysis of said physiologically acti
5277871 Liquid chromatographic analyzer, sample feeder and prelabeling reaction treating method January 11, 1994
The present invention provides a liquid chromatographic analyzer for analyzing a sample containing components for analysis by reacting the sample with a pre-labeling reagent to obtain a reaction mixture containing labeled components, concentrating the reaction mixture and separating the
5236847 Method for analyzing amino acids and apparatus therefor August 17, 1993
A method for analyzing amino acids in biological liquids wherein a buffer liquid including unknown components to be analyzed is introduced to a separation column for separating amino acids. After reaction of the buffer liquid in a reactor, the amino acids are detected by a photometer. Th
4238835 Analyzing apparatus with microcomputer December 9, 1980
An analyzing apparatus is controlled by a microcomputer which reads out programmed information from a magnetic card. The magnetic card does not always travel at a constant speed, and therefore, it is difficult for the microcomputer to entirely resort to the software for carrying out the
