    摘要: A preparative separation chromatograph system having a column for temporally separating components in a sample and for discharging an eluate fluid with the components, a detector for obtaining an absorbance spectrum of the eluate fluid, and a fraction collector for continuously creating a chromatogram. The system further includes: a peak section determiner; a differential value determiner for calculating a differential spectrum value and for determining whether or not the absolute value of the differential spectrum value is equal to or less than a predetermined value; and a fraction collector controller for controlling the fraction collector so as to fractionate the eluate fluid during a period of time for which it is determined that the chromatogram peak of the target component is present and for which it is also determined the absolute value of the differential spectrum value is equal to or less than the predetermined value.

    摘要: A chromatographic interface for sample handling and manipulation between separations or analyses is provided. The interface has an interfacing unit, a sample acquisition unit, and a sample trapping unit. The sample acquisition unit includes an inflow selector valve, an outflow selector valve, and one or more collection loops. The sample trapping unit includes a trap in fluid communication with the loop and having a stationary phase. The stationary phase can trap an analyte of interest from a fraction of the chromatographic sample separation flow. The tapping unit also has a scavenging gas source and a vacuum source; both can be used to substantially dry the stationary phase.

    摘要: A system and process for chromatography that uses a chromatography column to separate components from a sample received into the column in a mobile phase flowstream and places a second chromatography column between a detector and a collection system that compensates the timing of fraction collection for a delay caused by processing the collection signals generated by the detector. The device and process of the preferred and alternative embodiments add a delay into the flowstream of a chromatographic system, such as LC, HPLC, and SFC. Sample fractions are collected from sample component concentration peaks based upon the chromatographic elution of the sample components.

    摘要: A fraction collection system for liquid chromatography includes a conduit, which directs a sample eluent from an LC column through a flow splitter to a destructive analytical detector such as a mass spectrometer to analyze sample components, and to a fraction collector. A nondestructive detector such as a photodetector is positioned near the fraction collector to detect arrival of sample components. Optionally, a nondestructive detector such as a photodetector is situated upstream from the splitter, to detect passing sample components. Time intervals between detection of a calibrant or a sample component at any two of the detectors provide for automatable identification of selected sample components at the sample collector.

    摘要: A method and apparatus for high-throughput identity confirmation, quantitation and purity determination of a compound of interest in a mixture of compounds is disclosed. According to the method, a chemical mixture, such as may be obtained from a chemical library, is processed to obtain a stream having a time-varying composition, such as by using a high pressure liquid chromatograph. The stream is split into two portions or streams for substantially contemporaneous detection in a compound-identifying device, such as a mass spectrograph, and in a compound-quantitating device, such as an evaporative light scattering detector. A peak in a chromatogram obtained from the compound-quantitating device is identified as the compound of interest by cross-correlation, via elution time, with chromatographic results obtained from the compound-identifying device. Once the peak is identified as corresponding to the compound of interest, the corresponding peak area is used for quantitation and purity determination.
