发明名称 Chromatography using multiple detectors
摘要 Methods and related apparatuses and mixtures are described for chromatographic analysis. The described system includes a pressurized source of a mobile phase and a flow path in fluid communication with the pressurized source such that the mobile phase flows through the flow path. The system also includes an injector in fluid communication with the flow path and downstream of the pressurized source, the injector being configured to inject a sample into the flow path. A first column located downstream of the injector, contains a stationary phase, and forms part of the flow path. A first detector is positioned to detect properties of fluid in the flow path at a location downstream of the injector and upstream from the first column. A second detector is positioned to detect properties of fluid in the flow path at a location downstream of the first column.

主权项 1. A system for chromatographic analysis of a sample containing a plurality of components, the system comprising: a pressurized source of a mobile phase; a flow path in fluid communication with the pressurized source such that the mobile phase flows through the flow path; an injector in fluid communication with the flow path and downstream of the pressurized source, the injector configured to inject the sample into the flow path; a first column containing a stationary phase and forming part of the flow path, the first column being located downstream of the injector; a first detector in fluid communication with the flow path, and positioned to detect properties of fluid in the flow path at a location downstream of the injector and upstream from the first column; a second detector in fluid communication with flow path, and positioned to detect properties of fluid in the flow path at a location downstream of the first column; and a processor configured to receive first peak measurement data from the first detector and second measurement data from the second detector and combine the first and second peak measurement data to calculate a property associated with at least one of the components of the sample.
