Abstract: The disclosure relates to a system for liquid sample introduction into a chromatography system. The system includes a syringe, a first valve in fluid communication with the syringe, a second valve in fluid communication with the sample, a vessel located between, and in fluid communication with, the first and second valves, a third valve in fluid communication with the first valve, the second valve and a chromatography column, and a pump in fluid communication with the third valve and a mobile phase. When the valves are in a first position the syringe draws the sample into the vessel. The mobile phase flows to the chromatography column. When the valves are in a second position, a portion of the mobile phase flows into the vessel, mixing with and pressurizing the sample. When the valves are in a third position, the mixed and pressurized sample flows to the chromatography column.

Abstract: Described is a coupling seal that includes a polymeric body having a bore extending from a first end to an internal sealing surface and a fluid channel extending from the internal sealing surface to a second end. The bore is configured to receive a tube having a fluid channel so that an endface of the tube engages the internal sealing surface. The second end of the polymeric body is configured to contact a sealing surface of a coupling body that has a fluid channel extending from the sealing surface. A fluidic seal occurs when the coupling seal is compressed between the endface and the sealing surface. A void between an outer surface of the polymeric body and an inner surface of the coupling body receives the deformation of the coupling seal while under compression to thereby prevent the fluid channel of the tube from being crushed or obstructed.

Abstract: A check valve comprises a valve seat element along a fluid path that is formed of a polymeric material and comprises a hole that extends from an input end of the valve seat element to an output end of the valve seat element. The valve seat element includes an inner taper that transitions the input end to the output end, the valve seat element including a sealing surface along the inner taper. A poppet body is formed of a polymeric material and configured to engage the internal tapered sealing surface of the valve seat element. The poppet body moves between a first position at which the poppet body sealingly engages the tapered sealing surface of the valve seat element and a second position at which the poppet body is separate from the inner taper of the valve seat member.

Abstract: Described are a method and a system for diluting a sample at a location of injection in a liquid chromatography system. The method includes loading a sample into a first fluid channel, separating a flow of a mobile phase into a first flow in the first fluid channel and a second flow in a second fluid channel, and combining the sample that is displaced from the first fluid channel and the mobile phase exiting the second fluid channel at the location of injection into the system flow to thereby generate a diluted sample in the system flow. The dilution ratio of the diluted sample is responsive to the flow rates of the first and second flows. Advantageously, the flow rates can be changed by changing the flow restriction of one of the fluid channels. Thus providing the proper flow restriction enables a user to obtain a desired dilution ratio.

Abstract: A chromatography system includes a gradient delay volume defined as an overall fluid volume between where gradient is proportioned until an inlet of a chromatography column, a pump pumping a flow of gradient; and at least one valve located downstream from the pump, the at least one valve having a plurality of ports including an inlet port that receives the flow of gradient from the pump and an outlet port through which the flow of gradient exits the at least one valve, the at least one valve having at least two positions. A first position of the at least two positions of the at least one valve increases the gradient delay volume of the chromatography system relative to when the at least one valve is in a second position.

Abstract: Described are a method and a system for injecting a sample into a flow of a liquid chromatography system. The method includes combining a flow of a sample and a flow of a mobile phase to create a diluted sample in the system flow. The volumetric flow rate of the sample is controlled to be at a value that yields a desired dilution ratio for the diluted sample. The particular value at which the volumetric flow rate is maintained can be determined from the desired value of the dilution ratio and the volumetric flow rate of the mobile phase. System embodiments include a syringe that can be used to provide a sample solution at a controllable volumetric flow rate for combination with a high pressure mobile phase.

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.
