摘要： A fraction collection system includes one or more chromatography columns. The system also includes one or more fraction collectors for collecting effluent from the columns. The fraction collectors include several racks, each holding a set of collection receptacles. A control system interfaces with the fraction collectors to implement experiments. The control system provides a user interface with which users can schedule runs. The user interface includes a graphical representation of the racks and tubes of the fraction collectors. Users can schedule runs to groups of tubes, and a visual attribute of the representation of the tube in the user interface is updated to indicate that the tubes are assigned to a run.

摘要： A main controller 201 of a main substrate 20 performs serial communications with a sub controller 214 of each flowrate control substrate 21. The flowrate of the carrier gas is controlled with the flowrate control circuit 213 under the control performed by each sub controller 214. Thus, the main controller 201 only needs to execute the processing of performing the serial communications with each sub controller 214. As a result, the processing executed by the main controller 201 can be reduced, and the processing executed by the main controller 201 is less likely to overwhelm its processing capability even when the number of flowrate control substrates 21 is increased. In addition, a signal line 40 between the main controller 201 and each sub controller 214 can be made long. Thus, the distance between the main substrate 20 and each of the flowrate control substrates 21 can be made long.

摘要： The invention relates to analysing and controlling collection of liquid eluate output from a separation process, in particular by use of a measure of suspended material in the eluate based on a light scattering detection method. Exemplary embodiments include a method (300) of controlling collection of a sample of a liquid eluate output from a separation process, the method comprising: exposing (306) the liquid eluate to light from a light source; detecting (307) light from the light source scattered by suspended material in the eluate at a detector; and beginning and ending collection (310) of the sample when a measure of the suspended material derived from the detected scattered light enters and leaves a predetermined range.

摘要： A supercritical fluid chromatography system comprises a first pump for pumping a first flow stream comprising a compressible fluid and a second pump for pumping a second flow stream comprising a modifier fluid. The second pump is in parallel with the first pump. A column is located in a combined flow stream. The column is located downstream of the first and second pumps. The combined flow stream comprises the first flow stream, the second flow stream, and a sample. A detector is located downstream of the column. A gas-liquid separator is located downstream of the detector. The gas-liquid separator is configured to vent a majority of the compressible fluid while maintaining a majority of the sample, thus preventing aerosolization of the flow stream and minimizing sample loss as well as cross contamination. An open bed collector is located after the gas-liquid separator.
