摘要： A fluid separation apparatus suitable for separating a mixed fluid with different properties and capable of separating a complex fluid mixture efficiently is provided. The fluid separation apparatus includes a sampling entrance, a first separation column, a second separation column, a bypass line, a detector and a guide multi-channel valve. A mixed fluid flows into the first separation column via the sampling entrance. The second separation column is connected to the first separation column in series and connected to the bypass line in parallel. The detector is connected to the second separation column and the bypass line. The guide multi-channel valve has different modes to control a flow-through status and a closed status between the first separation column and the second separation column, between the first separation column and the bypass line, between the second separation column and the detector, and between the bypass line and the detector.

摘要： A vented filter is placed at the HPLC (High Performance Liquid Chromatography) loop entry port of an HPLC injector valve. The vented filter prevents the push gas used to deliver the crude radiolabeled product from over-pushing the liquid to waste. Push gas is vented off when the entire crude liquid product has passed through the vented filter and been loaded onto the HPLC loop.

摘要： In a gas chromatograph, an injected sample for analysis (3) is passed through a separation device (5) to separate components present in the sample; at the end of the separation device, selected components are detected by a detector (12) and determined quantitatively on the basis of the detector signal (13) supplied by the detector. To permit validation and also to increase the accuracy of the analysis, the sample (3) is determined nondestructively by an additional detector (16) upstream from the separation device (5) and is determined quantitatively on the basis of the additional detector signal (17) supplied by the additional detector (16). The result of the quantitative determination of the sample (3) is used to verify the analysis.

摘要： In this device, for sweeping and injecting samples into the separation column of a chromatography apparatus, the separation column is secured to an opening connecting with a conduit which feeds a stream of carrier liquid to the device. The device subdivides a stream of carrier liquid into a primary stream and a secondary stream and feeds the primary stream over the entire cross section of the entrance to a separation column. Simultaneously feed of the secondary stream axially to the entrance of the separation column is performed while introducing the sample into the secondary stream. The device is usable particularly in liquid-phase chromatography.

摘要： A sampling device for extracting a sample to be analyzed having a volume less than 0.01 microliter from a fluid stream by selectively introducing a slideably supported shaft into the fluid stream to expose a sample retaining capillary hole in the shaft to the fluid stream. An ultrasonic oscillator is positioned in the the fluid stream to add vibrational energy thereto to force a liquid sample into the capillary hole. The shaft is, subsequently, withdrawn from the fluid stream to deliver the fluid sample to a fluid analyzing means.

摘要： A significant reduction in extra-column band broadening can be achieved by decoupling the injection system from the main solvent flow line. Systems and methods for such decoupling can allow for the injection of larger volumes of sample without compromising separation yield, increase the column loading per batch, and increase the overall yield of separations. For example, a mixture of co-solvent and sample can be prepared separately from the main flow of mobile phase and co-solvent (e.g., a mixture of CO2 and methanol), loaded onto an injection loop, and then injected directly into the main flow of mobile phase and co-solvent before the chromatography column.
