<p>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.</p> |
