摘要： The present invention relates to a fluidic system for fraction collection. The fluidic system comprises a switching valve comprising a plurality of ports, wherein the switching valve is configured for connecting the ports in different configurations, wherein the ports comprise a first port (0) and a second port (2), an inlet line directly connected to the first port (0), and a collection device directly connected to the second port (2). The fluidic system is configured to assume a collection configuration, wherein the first port (0) and the second port (2) are connected. The ports further comprise a third port (4) and a fourth port (1), and the fluidic system further comprises a buffer section directly connected to the third port (4) and the fourth port (1). The fluidic system further comprises a first collection reservoir, wherein the fluidic system is configured to position the collection device to expel a fluid into the first collection reservoir. The fluidic system is further configured to assume a buffer configuration causing a fluid flow flowing through the inlet line, the first port (0), the third port (4), the buffer section, the fourth port (1), the second port (2), and the collection device in the buffer configuration. The present invention also relates to a computer program product to be used together with the fluidic system, and to corresponding methods.

摘要： An improved method and apparatus for identifying peaks and for determining the boundaries of those peaks, and boundaries of multiple peaks and shoulders within chromatograms (184). The method and apparatus effects real time identification and determination of the boundaries of these peaks for the purpose of fraction collection. The method and apparatus determines the boundary of a peak within a detector response profile that comprises data points plotted graphically on an X and Y-axis wherein the X-axis represents a first variable and the Y-axis represents a second variable, each variable having a value. The plot at each of the data points has a slope. Data points having a slope which deviates from a consistent value define a peak, and data points having a slope with a consistent value define a baseline.

摘要： A method and apparatus is disclosed to prepare a sample or a plurality of samples for subsequent analysis. A single sample deposition apparatus, and a multiplexed sample deposition apparatus are shown. The apparatus allows for a system that can provide a high throughput deposition of samples to form chromatograms by discrete droplet deposition or as continuous traces. The system can achieve high resolution digitization by pulsing the fluid emanating from the chromatographs by applying a voltage to the target plate that operates at frequencies equal to or greater than about 10 Hz, and up to and including about 1 KHz. The system also allows for analogue recording (i.e., approaching infinite resolution) by nebulizing the fluid coming from multiple columns and simultaneously collecting it on a target plate as a continuous trace.

摘要： The present invention provides a device and method for the purification and separation of substances. The purification device comprises a sample holder comprising a sample chamber and a column module. The column module is securable to the sample holder and is packed with chromatography medium having a special affinity for attracting a given substance. A variety of mediums can be used in the capsule of the purification device, each containing different medium types. The column modules may be prepacked by the manufacturer or may be provided empty so that a user defined medium may be inserted into the capsule by the user. With the column module and sample loaded, pressure may be applied to move the sample through the module to by means such as centrifuging in order to separate the selected substance from the sample.

摘要： A detection signal from a multi-wavelength detector provided in a liquid chromatograph is stored in a data storage part, and a chromatogram is formed from the stored data with respect to a specific wavelength, to detect a peak from the chromatogram. The spectrum at a top of the peak to be identified or a known spectrum of a component to be identified is used as a reference spectrum, to calculate the degree of coincidence between the spectrum at each position of the chromatogram peak and the reference spectrum as fraction purity at each position of the chromatogram peak. The calculated fraction purity values are classified in colors, for example, and displayed on a display part. Thus, it is possible to readily decide whether the measured peak consists of a single component or at least two components, and which time range consists of a single component.
