Abstract: A sampling system comprising an external sampling assembly in fluidic communication with a process sample manager is provided herein. The sampling system can automatically acquire sample from one or more sources of sample to prepare sample for injection into a column or detector. The external sampling assembly has an external sampling valve connected to an external pump and is in fluidic communication with a process sample manager. The external sampling valve has a first configuration and a second configuration useful in three steps of drawing, loading and discharging sample. Two selection valves can be connected to a plurality of external sampling valves for sequential sampling of multiple sources of sample. Sample can also be diluted in the process sample manager and then combined in a solvent composition stream for injection into the column or the detector.

Abstract: Described is a mobile phase fitting having reduced corrosion and erosion. The fitting includes a coupling body, compression screw, compression member and gasket. The coupling body has a threaded bore at one end, a tapered cavity, a narrow bore and a fluid channel. The compression screw has an axial bore to receive a tube and a threaded outer surface in engagement with the threaded bore of the coupling body. The compression member is disposed in the tapered cavity and has an axial opening to pass the tube and a tapered surface to engage a surface of the tapered cavity. The gasket is disposed in the narrow bore and has one surface in contact with the first internal surface and has a parallel surface to receive an end face of the tube. Mobile phase flows along a path that includes the tube, an opening in the gasket and the fluid channel.

Abstract: Process sample and dilution systems automatically draw sample from a reactor or other source of sample and prepare drawn sample for subsequent injection to a chromatographic column or a detector. The process sample and dilution system has an external pump valve assembly in fluidic communication with a process sample manager. The external pump valve assembly includes an external sampling valve, an external process valve, external pump and a mixing tee. The external sampling valve can be configured to automatically acquire sample from a reactor or other source of sample. The external pump discharges wash from the external process valve whereby sample is discharged from the external sampling valve to the mixing tee for quenching and dilution and subsequent processing by the process sample manager.
